Abstract
AIMS Studying crypt branching in ulcerative colitis (UC) and in infectious colitis (IC), we detected previously unreported crypt-associated anomalies (CAAs). The objective was to describe, illustrate and assess the frequency of CAAs in inflamed colon mucosa in patients with UC and IC. METHODS Sections from 100 consecutive biopsies with UC, in 50 with IC and in 27 with UC in remission (UCR) were reviewed. The following CAAs were identified: crypt eosinophilia, intracryptal epithelial hyperplasia, intracryptal epithelial budding, intracryptal supernumerary crypts, intracryptal epithelial bridges, crypt rings in rows and off-centre epithelial budding. RESULTS The frequency of crypts with extensive crypt eosinophilia and with intracryptal epithelial budding was significantly higher in UC than in IC and UCR (p<0.05); the frequency in the remaining histological parameters was similar in UC, IC and UCR. CONCLUSIONS CAAs were found interspersed with branching crypts. CAAs persisted in long-lasting UC mucosal inflammation, but declined when the inflammation waned. Since similar anomalies are not present in normal colon mucosa, the results suggest that CAAs had been boosted by the ongoing mucosal inflammation. The development of these previously unreported CAAs in the colon mucosa with inflammation might embody pathological aberrations of cryptogenesis.

Abstract
Ulcerative colitis is one of the two main subtypes of inflammatory bowel disease, along with Crohn's disease. Understanding the clinical and endoscopic features of ulcerative colitis is critical in achieving a timely diagnosis. An initial evaluation includes assessing clinical symptoms, inflammatory markers, endoscopic findings, and determination of the presence or absence of extraintestinal manifestations. Initial disease management should consider disease severity at the time of diagnosis as well as prognostication, or the determination of risk factors present with a high likelihood of severe disease in the future. Once appropriate therapy has been initiated, ongoing monitoring is crucial, which may include repeated clinical assessments over time, measuring noninvasive markers of inflammation, and endoscopic and histologic reevaluation. An important aspect of disease monitoring in ulcerative colitis is dysplasia surveillance; there are many patient-specific risk factors which influence surveillance strategies. Utilizing appropriate surveillance techniques is necessary for early detection of dysplasia and colorectal neoplasia.

Abstract
Ulcerative colitis (UC) is characterized by continuous mucosal inflammation of the rectum, extending uninterrupted to a variable portion of the colon proximally. However, in some patients with distal colitis, a distinct pattern of skip inflammation (so-called patch) involves the cecum and/or appendiceal orifice, but data on this entity are contradictory, and its significance and prognosis are still debated. We identified 102 adult cases of left-sided UC with a cecal/periappendiceal patch and compared them to 102 controls (left-sided UC only) along clinicopathologic characteristics and disease outcomes. In multivariate analysis, patients with a patch were younger (median age: 31 vs. 41 y; P =0.004) and more likely to have rectosigmoid involvement only (58.8% vs. 28.4%; P <0.001), compared with patients without a patch. During follow-up, patients with a patch were more likely to be eventually diagnosed with Crohn disease (CD) (9.8% vs. 1.0%; P =0.022) and to show proximal extension of inflammation (35.6% vs. 10.0%; P =0.021), but showed no differences in rates of neoplasia, colectomy, or pharmacotherapy escalation. Kaplan-Meier analysis confirmed that patients with a biopsy diagnosis of cecal/periappendiceal patch were more likely to show proximal disease extension ( P <0.001) and to be diagnosed with CD ( P =0.008). In conclusion, cecal/periappendiceal skip inflammation in left-sided UC occurs more often in younger patients and in those with rectosigmoid involvement and is associated with proximal disease extension and, in a small fraction of cases, change of diagnosis to CD. However, it does not portend increased risk of neoplasia, pharmacotherapy escalation, or subsequent colectomy, compared with patients with left-sided UC only.

Abstract
Very early onset inflammatory bowel disease (VEO-IBD) is a clinical umbrella classification composed of IBD-like diseases encompassing both classic IBD (Crohn's disease and ulcerative colitis) and monogenic disorder, both arising before 6 years of age. VEO-IBD patients present significant clinical differences from IBD occurring in older children and in adults, including more severe disease, often unresponsive to conventional IBD therapy and a greater proportion of cases featuring an underlying genetic alteration. Histologic findings of gastrointestinal biopsies can show an IBD-like pattern (both Crohn's disease-like and ulcerative colitis-like pattern), an apoptotic-like and enterocolitis-like pattern. Findings of specific morphologic alterations, such as villous blunting, apoptosis, dense eosinophilic infiltrates, lack of plasma cells and severe glandular atrophy, can suggest a monogenic disorder. Moreover, individuals with monogenic disorders may develop significant problems such as primary immunodeficiency, impacting treatment options. Finally, IBD histology in childhood can differ from that in older patients and adults. This complexity makes a differential diagnosis between IBD and other pediatric diseases involving the gastrointestinal tract difficult, especially considering that histologic features can be similar between different diseases. Without an appropriate diagnosis, the clinical course of VEO-IBD has greater potential for escalated treatment regimens involving extensive surgery and more intensive medical therapies rather than specific therapy directed toward the underlying defect. For these reasons, a pattern-based histologic approach correlated with clinical and laboratory findings with a multidisciplinary approach is fundamental to reach a correct diagnosis in an adequate clinical context.

Abstract
Histologic sections from patients with inflammatory bowel disease (IBD) usually exhibit crypts with architectural distortions and branching crypts. It has been postulated that crypt branching should be assessed only in well-oriented, upright crypts. However, those crypts are mostly found in sections from colectomy specimens and colon mucosectomies. Sections from endoscopic biopsies are fortuitously cut in a horizontal plane, a procedure mostly revealing cross-cut crypt rings. In endoscopic biopsies from UC patients we previously detected cross-cut crypts heralding the crest domain of branching crypts. Recently, the scrutiny of biopsies from IBD patients revealed that branching-crest domains concurred either with crypts in symmetric branching, typified by twin, amalgamating back-to-back isometrics crypt-rings, or with crypts in asymmetric branching, characterized by ≥2 amalgamating anisometric crypt-rings; both symmetric and asymmetric branching-crest domains were encased by a thin muscularis mucosae. Quantitative studies in biopsies from Swedish and German patients with IBD showed that crypts in asymmetric branching outnumbered those in symmetric branching. Because crypt-branching seldom occurs in the normal colon in adults and considering that colon crypts typically divide once or twice during a lifetime, the accruing of asymmetric branching crypts in IBD biopsies emerges as a significant histologic parameter. Although the biological significance of asymmetric crypt-branching in IBD remains at present elusive, their occurrence deserves to be further investigated. The future policy will be to include in our pathologic reports, the number of crypts in asymmetric branching, in order to monitor their frequency in prospective surveillance biopsies in patients with IBD.

Abstract
Inflammatory bowel disease, including ulcerative colitis and Crohn disease, is an idiopathic chronic inflammatory condition of the gastrointestinal tract. Since neither the clinical manifestations nor the morphologic features of inflammatory bowel disease are pathognomonic alone, the differential diagnosis to consider is relatively broad, and it relies on the synthesis of clinical, endoscopic, and microscopic features. Long-held histologic diagnostic principles include recognizing structural and inflammatory features of chronicity, that is, architectural distortion, basal plasmacytosis, and expansion of the lamina propria lymphoplasmacytic infiltrate. In addition, evaluation of the neutrophilic inflammation and related crypt and epithelial destruction is essential to gauge the activity of the disease. Nevertheless, these features can be difficult to confirm in special settings, including at the inception of the disease or in partially treated cases. This review will explore the classic morphologic features of ulcerative colitis and Crohn disease, followed by a detailed discussion of atypical and diagnostically challenging presentations and a brief review of the clinical aspects necessary for the daily practice of pathologists.

Abstract
BACKGROUND Ulcerative colitis (UC) is characterised by mucosal inflammation from the rectum to its proximal area in a symmetric and continuous fashion. However, although uncommon, we encounter cases of UC with rectal sparing in the initial stage.
AIM To evaluate the clinical characteristics and clinical course for rectal sparing UC compared with typical UC.
METHODS We looked at records from 2004 to 2015, and selected patients who were newly diagnosed with UC, and who could be followed up for at least 5 years in our hospital. We then retrospectively analysed the medical records and endoscopic findings of those patients. To compare the clinical course and prognosis, we matched each patient with rectal sparing UC 1:3 with controls by age, sex, and disease extent.
RESULTS Of 619 UC patients, 24 (3.9%) showed rectal sparing at diagnosis. During the follow-up period (median 8 years), in two (8.3%) of the 24 patients, rectal sparing remained through follow-up inspections; but for the other 22 (91.7%) patients, obvious rectal inflammation was found at follow-up endoscopy. Of the 24 patients, 8 (33.3%) were initially misdiagnosed with infectious colitis. No diagnosis was changed to Crohn’s disease. The uses of corticosteroid or biologic agents, hospitalisation rate, and colectomy rates were not different between the rectal sparing UC group and typical UC group.
CONCLUSION Some patients with UC can reveal atypical patterns of disease distribution, such as rectal sparing in its initial stage; but despite this, the clinical course and prognosis may not differ from those of typical UC patients.

Abstract
Background: The association between inflammatory bowel disease (IBD) and immune thrombocytopenia (ITP) is still uncertain. In this multicenter retrospective study, the coexistence of both diseases was investigated in children diagnosed from 1 January 2000 to 31 December 2019. Methods: Clinical characteristics of both IBD and ITP, onset of disorders, and patient’s response to treatment were collected through a structured form sent to 55 Italian pediatric referring centers for hematological disorders. Result: Centers responded to the survey and reported the coexistence of IBD and ITP in 14 children. The first diagnosis was ITP in 57.1% and IBD in 35.7% of patients: it was simultaneous in 7.1%. IBD was classified as ulcerative colitis (57.1%), Crohn disease (35.7%), and unclassified (7.1%). No therapy for IBD other than steroids had any effect on ITP course. Colectomy resulted in recovery from ITP in 1 of the 2 patients surgically treated. ITP was always mild but turned to be chronic in half of patients. Conclusions: In all patients, ITP was mild without any evident impact on IBD severity, but the incidence of chronic ITP seems to be higher than what is usually observed in the pediatric age group. Colectomy had unpredictable effects on ITP.

Abstract
BACKGROUND AND AIMS Complete histological normalisation and reduction of inflammation severity in patients with ulcerative colitis are associated with improved clinical outcomes, but the clinical significance of normalisation of only segments of previously affected bowel is not known. We examined the prevalence, pattern, predictors, and clinical outcomes associated with segmental histological normalisation in in patients with ulcerative colitis. METHODS Medical records of patients with confirmed ulcerative colitis and more than one colonoscopy were sought. Segmental histological normalisation was defined as histological normalisation of a bowel segment [rectum, left-sided or right-sided colon] that had previous evidence of chronic histological injury. We assessed the variables influencing these findings and whether segmental normalisation was associated with improved clinical outcomes. RESULTS Of 646 patients, 32% had segmental and 10% complete histological normalisaton when compared with their maximal disease extent. Most [88%] had segmental normalisation in a proximal-to-distal direction. Others had distal-to-proximal or patchy normalisation. On multivariate analysis, only current smoking [p = 0.040] and age of diagnosis ≤16 years [p = 0.028] predicted segmental histological normalisation. Of 310 who were in clinical remission at initial colonoscopy, 77 [25%] experienced clinical relapse after median 1.3 [range 0.06-7.52] years. Only complete histological normalisation of the bowel was associated with improved relapse-free survival (hazard ratio [HR] 0.23; 95% confidence interval [CI] 0.08-0.68; p = 0.008]. CONCLUSIONS Segmental histological normalisation occurs in 32% of patients with ulcerative colitis and is increased in those who smoke or were diagnosed at younger age. Unlike complete histological normalisation, segmental normalisation does not signal improved clinical outcomes.

Abstract
BACKGROUND Microscopic ileitis and its association with pancolitis in adults with ulcerative colitis (UC) have been described. The incidence of ileitis and associations with colonic disease in pediatric UC have, however, not been thoroughly investigated. This study was undertaken to examine the prevalence of microscopic ileal inflammation at the time of initial diagnosis in a cohort of children with UC. METHODS We reviewed colonoscopy and biopsy data at time of diagnosis from 105 children and young adults with treatment naïve UC; ileal and colonic mucosal biopsies were available on all patients. Ileal mucosal biopsies were examined for the presence and severity of ileal inflammation, and other histologic features. Concurrently obtained colonic mucosal biopsies were assessed to define the severity, distribution, and extent of disease; endoscopic and clinical follow-up data were reviewed. RESULTS A total of 107 ileal mucosal biopsies and 693 corresponding colonic mucosal biopsies were examined. Seventeen of 105 patients (16%) were found to have ileal inflammation (mean age = 10.4 years, 59% girls), 14 (82%) of whom had histologic pancolitis. The presence of ileal inflammation was significantly associated with endoscopic pancolitis (P = 0.02). The association between histologic pancolitis, severity of active inflammation in the cecum, and ascending colon suggested a possible association with ileal inflammation (P = 0.06, 0.07, and 0.08 respectively), but did not reach statistical significance. CONCLUSION Patients with new onset UC may have microscopic ileal inflammation at time of diagnosis, even if the terminal ileum appears macroscopically normal. The presence of endoscopic pancolitis is associated with the presence of histologic ileitis. In contrast to existing studies in adults, an association between the presence of ileitis and the histologic severity or the histologic extent of colitis was not observed. Children with microscopic ileitis in the context of UC do not need to be reclassified as "indeterminate colitis" or Crohn disease.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) mainly consists of Crohn's disease (CD) and ulcerative colitis (UC). About 10%-15% of patients with IBD cannot be firmly diagnosed with CD or UC; hence, they are initially diagnosed as inflammatory bowel disease unclassified (IBD-U). Having a firm diagnosis is clearly preferred to guide treatment choices, and better understanding of the nature of IBD-U is required. METHODS We performed an analysis of a subset of pediatric subjects from an inception IBD cohort of patients initially enrolled in a prospective multicenter study (the RISK study). Initial diagnosis and 2-year follow-up data from the subjects diagnosed with IBD-U were analyzed. An expert panel verified final diagnosis using predefined criteria as a guide. Serological and disease-relevant ileal and rectal tissue gene expression profiles were investigated. The use and the time to initiate anti-TNFα treatment was analyzed among the outcome groups. RESULTS A total of 1411 subjects were enrolled with initial diagnosis of IBD, and among them, 136 subjects were initially diagnosed as IBD-U at enrollment. And 26% were reclassified as UC and 14% as CD within 2 years of diagnosis, while 60% remained as IBD-U. Of those who were reclassified, there was a 2:1 ratio, UC (n = 35) to CD (n = 19). The molecular and serological features of IBD-U at the end of follow-up were very similar to UC and very different from CD. There was less likelihood of receiving anti-TNFα agents if the diagnosis was IBD-U compared with CD (P < 0.0001). CONCLUSIONS In our cohort, 60% of the IBD-U subjects remained as unclassified at 2 years; of those subsequently classified, a higher percentage followed a course more similar to UC. Most of the IBD-U subjects at diagnosis had serological and molecular signatures that are very similar to UC. Although the atypical presentations made the clinician to make an interim diagnosis of IBD-U, results of the molecular and serological factors performed at the time of diagnosis suggests that they were very similar to UC. However, long-term studies are needed to better understand the natural history and molecular characterization of pediatric onset IBD-U. 10.1093/ibd/izy136_video1Video 1.Video 1.

Abstract
OBJECTIVES The aims of this retrospective study were to describe ulcerative colitis (UC) phenotype at diagnosis and follow-up and to identify possible predictors of severe disease course. METHODS This was a retrospective, single-center study. We reviewed the charts of patients with UC diagnosed between 2 and 18 years at our referral center from January 2007 to January 2016. Laboratory and clinical features at diagnosis, such as disease extent, atypical phenotypes, extraintestinal manifestations, and therapies, and pattern changes during the follow-up, including relapse rate, disease extension, and the cumulative risk for colectomy were collected. RESULTS One hundred eleven patients were enrolled. Atypical phenotypes were identified at diagnosis in 55 out of 111 patients (49.5%). Extraintestinal manifestations were detected in 16 out of 111 (14.4%) at the diagnosis. During the follow-up 60 out of 111 (54%) patients needed to start azathioprine, 9 out of 111 (8.1%) patients started biologic therapy and 10 out of 111 (patients underwent surgery, resulting in a cumulative risk of 8% at 5 years and 16% at 10 years. Steroid refractoriness (hazard ratio: 13.9) and starting of biologic therapy (hazard ratio: 25.3) represented the best predictors for surgery. The cumulative probability of first relapse was 47% at 6 months and 63% at 1 year. Disease extension was reported in 21 out of 70 patients (30%). CONCLUSION Pediatric UC is associated with a severe phenotype and a high percentage of atypical features. Surgery rate seems to be decreased from early reports.

Abstract
BACKGROUND AND AIM In some patients with ulcerative proctitis (UP), skip inflammation is noted in the right side of the colon, but little is known about its clinical course. The aim of this study was to evaluate the clinical course of UP with skip inflammation and the efficacy of topical 5-aminosalicylate (5-ASA) monotherapy. METHODS This study reviewed the data of 388 patients with an initial diagnosis of UP from January 2005 to October 2015. This study matched each UP patient with skip inflammation 1:2 with controls who had UP without skip inflammation; to reduce bias, this study matched the controls with the cases by age, gender, and initial disease activity. RESULTS During the follow-up period (median: 69.5 months), the overall progression rates for the control group (n = 192) and the skip inflammation group (n = 96) were 24.0% and 32.9% at 10 years, respectively (log-rank P = 0.71). In the skip inflammation group, the progression rates were not significantly different between the 5-ASA combination group and the topical group, 33.4% and 26.6% at 10 years, respectively (log-rank P = 0.96). The overall acute exacerbation rates for the control and skip inflammation groups were 17.2% and 26.8% at 10 years, respectively (log-rank P = 0.68). In the skip inflammation group, the exacerbation rates were also not significantly different between the combination and topical treatment groups, 26.6% and 23.6% at 10 years, respectively (log-rank P = 0.88). CONCLUSION The clinical course of UP with skip inflammation was not different from that of typical UP, and topical 5-ASA monotherapy for maintaining remission was as effective as 5-ASA combination therapy irrespective of the presence of skip lesions.

Abstract
OBJECTIVES Differentiating ulcerative colitis (UC) and Crohn disease (CD) can be clinically challenging, especially in children. Granulomatous inflammation has traditionally been attributed to CD. Crypt-associated giant cells and granulomas, however, have been observed in colonic biopsies of patients with UC. This phenomenon has not been described in the upper gastrointestinal (UGI) tract with UC. METHODS Seven pediatric patients with UC with granulomatous UGI (gUGI) lesions were identified. Diagnosis of UC was based on symptoms, clinical course, laboratory results, imaging, and endoscopy. We compared the gUGI patients to a large cohort of pediatric patients with UC (n = 149). RESULTS All fully evaluated cases were associated with bloody diarrhea and moderate to severe pancolitis. Gastric and/or duodenal biopsies demonstrated giant cells or granulomas near gland destruction. Small bowel imaging did not reveal any involvement. The majority of cases responded to standard medical therapies, except for 2 patients (28.6%) who required total colectomy. Acute severe, refractory colitis (ie, colectomy within 1 month of presentation) was significantly more common in the gUGI group than the large pediatric UC group (28.6% vs 1.3%, Fisher exact P = 0.01). CONCLUSIONS This is the first report of pediatric UC-associated granulomatous inflammation in the UGI tract. We speculate that these lesions represent extracolonic manifestations of intense colonic disease. These atypical findings expand the diagnostic considerations that should be incorporated during the differentiation between UC and CD in the pediatric age group.

Abstract
Histopathological assessment of biopsy and resection specimens of chronic inflammatory bowel disease (CIBD), or possible CIBD, forms a significant component of the routine workload in most tissue pathology laboratories. In this review, we have chosen selected areas of particular diagnostic difficulty in CIBD pathology, providing key advice for pathology reporting. Those mimics of CIBD which have the greatest potential for misdiagnosis are discussed, particularly the wide range of infectious colitides which represent possible diagnostic pitfalls. The most important distinguishing features between the two main forms of CIBD, ulcerative colitis and Crohn's disease, are addressed, first in relation to resection specimens, and then with emphasis on features which may also be diagnostically useful in endoscopic biopsy material. The importance of assessment of the index endoscopic specimen is stressed, before treatment has been instigated, along with careful correlation with clinical and endoscopic features. Problems in the assessment of post-surgical CIBD specimens are described and then the role of upper gastrointestinal pathology specimens in diagnosing both Crohn's disease and ulcerative colitis, with increased recognition of upper gastrointestinal tract involvement in the latter condition. Finally, with recent developments in endoscopic surveillance techniques and local excision options, modern approaches to reporting and managing neoplasia complicating CIBD are reviewed.

Abstract
To characterize rectal histology in an inception cohort of children newly diagnosed with ulcerative colitis (UC) and to explore its relationship with clinical indices of disease severity. The PROTECT (Predicting Response to Standardized Pediatric Colitis Therapy) Study enrolled children 17 years of age and younger newly diagnosed with UC. Baseline rectal biopsies were evaluated for acute and chronic inflammation, eosinophilic inflammation (peak eosinophil count > 32 eosinophils/high powered field, eosinophilic cryptitis or abscesses), and architectural/nonarchitectural chronic changes. Correlation with clinical indices including Mayo endoscopy subscore and Pediatric Ulcerative Colitis Activity Index was performed. Rectal biopsies from 369 patients (mean age, 12.9±3.1 y, 50% female) were reviewed. Cryptitis was found in 89%, crypt abscesses in 25%, and eosinophilic inflammation in 58%. Crypt distortion/atrophy was present in 98% of specimens. Higher grades of acute and chronic inflammation were associated with the presence of basal plasmacytosis (P<0.0001), basal lymphoid aggregates (P<0.0001), and surface villiform changes (P<0.0001). A severe Mayo endoscopy subscore was most common among those with severe acute and chronic inflammation, although this relationship was not linear. Severe Pediatric Ulcerative Colitis Activity Index scores were associated with the absence of or only mild eosinophilic inflammation (<32 eosinophils/high powered field) (P<0.03) and the presence of surface villiform changes (P<0.005). Acute and chronic inflammation, eosinophilic inflammation and chronic changes are common in children newly diagnosed with UC. The clinical and biological implication of low to absent eosinophilic inflammation and the presence of surface villiform changes requires further study.

Abstract
Background Ulcerative colitis (UC) is known as an immune disorder of the colon that generally involves the rectum, but an atypical distribution of inflamed mucosa has previously been noted in certain subtypes of UC, such as the rectal-sparing type (RST). As noted in a previous report, patients with the RST may be at elevated risk for disease refractoriness, but the clinical significance of RST remains unknown. Methods UC patients who underwent surgery between January 2010 and April 2015 were included. Patients were classified as having the RST or a non-RST based on colectomy specimens or a pre-operative endoscopy. Possible risk factors for urgent/emergent surgery were analyzed. We specifically determined whether the RST is a significant predictor for urgent/emergent surgery. Results In total, 46/482 patients were classified as having the RST. Disease severity was significantly worse in patients with the RST than in other patients (p = 0.02). Urgent/emergent surgery was required for 24/46 patients with the RST, compared with 107/436 non-RST patients (p < 0.01). The overall incidence of urgent/emergent surgery was 131/482. Disease duration < 70.2 months [odds ratio (OR) 2.45], severe disease (OR 87.1), total administered steroid dose < 5000 mg (OR 3.02), daily pre-operative steroid dose ≥ 9 mg (OR 2.59), and the RST (OR 5.59) were identified as independent risk factors for urgent/emergent surgery. Conclusion The RST was an independent risk factor for urgent/emergent surgery in our analysis of surgically treated patients with UC.

Abstract
CONTEXT -Idiopathic inflammatory bowel disease manifests with different clinical phenotypes showing varying behavior and risk for neoplasia. The clinical questions that are posed to pathologists differ depending on phase of the disease and the clinical circumstances. Understanding the clinical aspects of the dynamic disease process will enhance the role of pathology in optimizing the care of patients with inflammatory bowel disease. OBJECTIVE -To review clinical and surgical aspects of inflammatory bowel disease that are relevant to practicing pathologists. DATA SOURCES -The literature was reviewed. CONCLUSIONS -Diagnosis and management of inflammatory bowel disease require an integrated evaluation of clinical, endoscopic, radiologic, and pathologic features. Therefore, close interaction between clinicians and pathologists is crucial. Having this team approach improves understanding of the pertinent clinical and surgical aspects of the disease and assists in the recognition of unusual presentation of variants, as well as mimics of idiopathic inflammatory bowel disease, by pathologists.

Abstract
In a patient presenting with suspected inflammatory bowel disease, the initial endoscopic evaluation is a valuable tool for determining the correct disease diagnosis and the extent and severity of disease. A full colonoscopy and ileoscopy should be performed when possible, with systematic biopsies from each segment. When a diagnosis of inflammatory bowel disease is established, it is possible to distinguish between Crohn disease and ulcerative colitis, and specific endoscopic features may assist in this categorization. Because patchy healing can occur with treatment, it is important to obtain a thorough and accurate assessment of disease characteristics and distribution before initiating therapy.

Abstract
Background Early manifestations of pediatric inflammatory bowel disease (IBD) can be relatively nonspecific. Initial mucosal biopsies may not be conclusive, delaying the diagnosis until subsequent biopsies demonstrate typical histologic features of IBD. We hypothesized that certain inflammatory cell types may be utilized as early histologic indicators of IBD in children. Methods A retrospective analysis compared histologic findings from initially inconclusive or negative endoscopic studies in 22 patients who were subsequently diagnosed with IBD (after diagnostic endoscopy) to those of 20 comparison patients with functional abdominal pain matched for age, gender, and study type. A pediatric pathologist, blinded to study group, reviewed biopsies for histologic abnormalities. Eosinophil densities were obtained from the stomach, duodenum, and rectosigmoid areas. Immunohistochemistry (IHC) staining for tumor necrosis factor-α (TNF-α) and matrix metalloproteinase-9 (MMP-9) was performed on the stomach and rectosigmoid areas. Results Gastritis and colonic crypt distortion were present in the IBD group at a greater rate (61 % vs. 22 %, p = 0.020; 34 % vs. 4 %, p = 0.008, respectively). Peak and mean eosinophil densities in the rectosigmoid area were greater in the IBD group (17.0/hpf vs. 5.0/hpf, p = 0.0063; 12.3/hpf vs. 4.2/hpf, p = 0.0106, respectively). TNF-α and MMP-9 staining did not reveal any significant differences. Conclusions Our data suggests that significantly greater inflammation in the stomach, crypt distortion in the colon, and eosinophilia in the rectosigmoid distinguished the IBD group from the comparison group at the time of the initial endoscopic evaluation.

Abstract
Distinguishing ulcerative colitis (UC) from Crohn's disease (CD) is normally based on evaluation of a variety of clinical, radiologic, serologic and pathologic findings, the latter in biopsy and/or resection specimens. Unfortunately, some patients with IBD show overlapping pathologic features of UC and CD, which makes definite distinction between these two disorders difficult or even impossible. In most instances of uncertainty, the patient shows clinical and pathologic features of UC, but in addition, the patient's colon resection specimen reveals one or more CD-like features. In this setting, a diagnosis of indeterminate colitis (IC) is often rendered. IC is not a distinct disease entity, and, thus, it has no diagnostic criteria. The most common causes of uncertainty in IBD pathology that may lead to a diagnosis of IC in a colon resection specimen includes the presence of fulminant (severe and toxic) colitis, insufficient radiologic, endoscopic, or pathologic information (including analysis of prior biopsies) on the patient, failure to utilize major diagnostic criteria as hard evidence in favor of CD, failure to recognize unusual variants of UC and CD that may mimic each other, failure to recognize non-IBD mimics and other superimposed diseases that cause unusual pathologic features in a resection specimen, an attempt to distinguish UC from CD in mucosal biopsies of the colon and ileum, or an attempt to change the patients diagnosis (of UC or CD) based on pouch or diversion-related complications. Details of each of these causes of uncertainty are discussed, in detail, in this review article. A diagnosis of IC should never be made clinically or by pathologists based on evaluation of pre-resection colonic mucosal biopsies. Ultimately, the majority of indeterminate cases represent UC, and, thus, most of these patient can be treated safely with a colectomy combined with an ileal pouch anal anastomosis procedure.

Abstract
Accurate diagnosis of predominantly colonic inflammatory bowel disease (IBD) is not possible in 30% of patients. For decades, scientists have worked to find a solution to improve diagnostic accuracy for IBD, encompassing Crohn's colitis and ulcerative colitis. Evaluating protein patterns in surgical pathology colectomy specimens of colonic mucosal and submucosal compartments, individually, has potential for diagnostic medicine by identifying integrally independent, phenotype-specific cellular and molecular characteristics. Mass spectrometry (MS) and imaging (I) MS are analytical technologies that directly measure molecular species in clinical specimens, contributing to the in-depth understanding of biological molecules. The biometric-system complexity and functional diversity is well suited to proteomic and diagnostic studies. The direct analysis of cells and tissues by Matrix-Assisted-Laser Desorption/Ionization (MALDI) MS/IMS has relevant medical diagnostic potential. MALDI-MS/IMS detection generates molecular signatures obtained from specific cell types within tissue sections. Herein discussed is a perspective on the use of MALDI-MS/IMS and bioinformatics technologies for detection of molecular-biometric patterns and identification of differentiating proteins. I also discuss a perspective on the global challenge of transferring technologies to clinical laboratories dealing with IBD issues. The significance of serologic-immunometric advances is also discussed.

Abstract
This review summarizes diagnostic problems, challenges and advances in ulcerative colitis (UC). It emphasizes that, although histopathological examination plays a major role in the diagnosis and management of UC, it should always be interpreted in the context of clinical, endoscopic, and radiological findings. Accurate diagnosis requires knowledge of the classic morphological features of UC, as well as a number of atypical pathological presentations that may cause mis-classification of the disease process, either in resection or biopsy specimens. These atypical pathological presentations include rectal sparing and patchiness of disease at initial presentation of UC in pediatric patients or in the setting of medically treated UC, cecal or ascending colon inflammation in left-sided UC, and backwash ileitis in patients with severe ulcerative pancolitis. Loosely formed microgranulomas, with pale foamy histiocytes adjacent to a damaged crypt or eroded surface, should not be interpreted as evidence of Crohn's disease. Indeterminate colitis should only be used in colectomy specimens as a provisional pathological diagnosis. Patients with UC are at risk for the development of dysplasia and carcinoma; optimal outcomes in UC surveillance programs require familiarity with the diagnostic criteria and challenges relating to UC-associated dysplasia and malignancy. Colon biopsy from UC patients should always be evaluated for dysplasia based on cytological and architectural abnormalities. Accurate interpretation and classification of dysplasia in colon biopsy from UC patients as sporadic adenoma or UC-related dysplasia [flat, adenoma-like, or dysplasia-associated lesion or mass (DALM)] requires clinical and endoscopic correlation. Isolated polypoid dysplastic lesions are considered to be sporadic adenoma if occurring outside areas of histologically proven colitis, or adenoma-like dysplasia if occurring in the diseased segment. Recent data suggest that such lesions may be treated adequately by polypectomy in the absence of flat dysplasia in the patient. UC patients with DALM or flat high-grade dysplasia should be treated by colectomy because of the high probability of adenocarcinoma. The natural history of low-grade dysplasia (LGD) is more controversial: while multifocal LGD, particularly if detected at the time of initial endoscopic examination, is treated with colectomy, unifocal flat LGD detected during surveillance may be managed by close follow-up with increased surveillance. The surveillance interval and treatment options for UC patients with dysplasia are reviewed in detail.

Abstract
BACKGROUND Histological segmental distribution of ulcerative colitis (UC) may represent an early finding of newly diagnosed UC, especially in pediatric patients; a sign of Crohn's disease; or a predictor of refractory UC. However, its significance remains unknown. This study was performed to compare the final pathologic findings in resected total colon and rectum specimens between pediatric and adult patients with refractory UC who underwent proctocolectomy and clarify the significance of segmental distribution in pediatric patients with UC. METHODS Ninety patients with medically refractory UC (14 with childhood-onset UC and 76 with adult-onset UC) who underwent a two-staged operation comprising total proctocolectomy and ileal J-pouch anal anastomosis in the first stage were included in this study. We retrospectively reviewed all patients' medical records and performed a histological evaluation of the resected total colon using Geboes' grading system for histological inflammation activity of UC and factors of Tanaka's criteria for refractory UC. RESULTS Histological segmental distribution was more frequently observed in the resected colon at surgery in pediatric (64%) than in adult patients (21%) with refractory UC. The administration of immunomodulators or anti-TNF-α antibody within 30 days before surgery was more frequently performed in adults than in children. Patients with refractory UC with a segmental distribution had a statistically significant relationship with shorter duration before surgery (P = 0.0009), male gender (P = 0.0342), and higher activity of disease inflammation in rectum (P = 0.0399). Multivariate analysis revealed the statistically significant relationship between segmental distribution and disease duration before surgery ≤ 6 years (P = 0.0031). CONCLUSIONS Endoscopists should perform biopsies of both normal and abnormal mucosa throughout the total colon and follow changes in the pathological pattern because segmental distribution is an important predictor of prognosis.

Abstract
BACKGROUND The diagnosis of pediatric-onset inflammatory bowel disease (PIBD) can be challenging in choosing the most informative diagnostic tests and correctly classifying PIBD into its different subtypes. Recent advances in our understanding of the natural history and phenotype of PIBD, increasing availability of serological and fecal biomarkers, and the emergence of novel endoscopic and imaging technologies taken together have made the previous Porto criteria for the diagnosis of PIBD obsolete. METHODS We aimed to revise the original Porto criteria using an evidence-based approach and consensus process to yield specific practice recommendations for the diagnosis of PIBD. These revised criteria are based on the Paris classification of PIBD and the original Porto criteria while incorporating novel data, such as for serum and fecal biomarkers. A consensus of at least 80% of participants was achieved for all recommendations and the summary algorithm. RESULTS The revised criteria depart from existing criteria by defining 2 categories of ulcerative colitis (UC, typical and atypical); atypical phenotypes of UC should be treated as UC. A novel approach based on multiple criteria for diagnosing IBD-unclassified (IBD-U) is proposed. Specifically, these revised criteria recommend upper gastrointestinal endoscopy and ileocolonscopy for all suspected patients with PIBD, with small bowel imaging (unless typical UC after endoscopy and histology) by magnetic resonance enterography or wireless capsule endoscopy. CONCLUSIONS These revised Porto criteria for the diagnosis of PIBD have been developed to meet present challenges and developments in PIBD and provide up-to-date guidelines for the definition and diagnosis of the IBD spectrum.

Abstract
Background Paneth cell metaplasia (PCM) is well described in adults but little is known about the distribution of colonic Paneth cells and the occurrence of PCM in a paediatric population. The aim of this study is to determine whether Paneth cell hyperplasia or metaplasia characteristically occurs in the colons of children with newly diagnosed idiopathic inflammatory bowel disease (IBD). Methods We retrospectively reviewed colonic series from 28 new diagnoses of paediatric IBD at a tertiary referral centre, and from a further 14 children with IBD-like symptoms whose colonic biopsies and ancillary investigations were normal. Paneth cells were counted at 6 anatomical sites in the colon, and at each site acute and chronic inflammation were assessed semi-quantitatively and the presence or absence of crypt architectural distortion and eosinophilia was documented. Results In control, ulcerative colitis (UC) and Crohn’s disease (CD) groups there was a gradient of decreasing Paneth cell numbers from caecum to rectum. Paneth cells were not seen in the distal colon in the control group, but they were present there in 11 of 13 patients with ulcerative colitis and 14 of 15 with Crohn’s disease. Only patients with IBD showed Paneth cell hyperplasia, assessed as more than 10 Paneth cells per 10 well-oriented crypts at any site. There was a statistically significant increase in Paneth cells in the caecum, ascending, transverse and descending colon in UC and in the ascending, transverse, descending and sigmoid colon in CD compared with controls. There was no significant difference between UC and CD. There was no correlation between the site of PCM and acute or chronic inflammation, crypt distortion or eosinophilia. Conclusion Paneth cells are found in the proximal but not the distal colon in otherwise normal paediatric colonic series. A high proportion of UC and CD patients show PCM in the distal colon. This is present early in the disease and does not correlate with histological features of chronicity.

Abstract
Inflammatory bowel diseases (IBDs) are lifelong disorders predominantly present in developed countries. In their pathogenesis, an interaction between genetic and environmental factors is involved. This practice guide, prepared on behalf of the European Society of Pathology and the European Crohn's and Colitis Organisation, intends to provide a thorough basis for the histological evaluation of resection specimens and biopsy samples from patients with ulcerative colitis or Crohn's disease. Histopathologically, these diseases are characterised by the extent and the distribution of mucosal architectural abnormality, the cellularity of the lamina propria and the cell types present, but these features frequently overlap. If a definitive diagnosis is not possible, the term indeterminate colitis is used for resection specimens and the term inflammatory bowel disease unclassified for biopsies. Activity of disease is reflected by neutrophil granulocyte infiltration and epithelial damage. The evolution of the histological features that are useful for diagnosis is time- and disease-activity dependent: early disease and long-standing disease show different microscopic aspects. Likewise, the histopathology of childhood-onset IBD is distinctly different from adult-onset IBD. In the differential diagnosis of severe colitis refractory to immunosuppressive therapy, reactivation of latent cytomegalovirus (CMV) infection should be considered and CMV should be tested for in all patients. Finally, patients with longstanding IBD have an increased risk for the development of adenocarcinoma. Dysplasia is the universally used marker of an increased cancer risk, but inter-observer agreement is poor for the categories low-grade dysplasia and indefinite for dysplasia. A diagnosis of dysplasia should not be made by a single pathologist but needs to be confirmed by a pathologist with expertise in gastrointestinal pathology.

Abstract
BACKGROUND Inflammatory bowel disease (IBD) starting during childhood has been assumed to impair quality of life (QoL) of affected children. As this aspect is crucial for further personality development, the health-related quality of life (HRQOL) was assessed in a Swiss nationwide cohort to obtain detailed information on the fields of impairment. METHODS Data were prospectively acquired from pediatric patients included in the Swiss IBD Cohort Study. IBD activity was evaluated by PCDAI and PUCAI. The age adapted KIDSCREEN questionnaire was evaluated for 110 children with IBD (64 with Crohn's disease 46 with ulcerative colitis). Data were analyzed with respect to established reference values of healthy controls. RESULTS In the KIDSCREEN index a moderate impairment was only found for physical wellbeing due to disease activity. In contrast, mental well-being and social support were even better as compared to control values. A subgroup analysis revealed that this observation was restricted to the children in the German speaking part of Switzerland, whereas there was no difference compared to controls in the French part of Switzerland. Furthermore, autonomy and school variables were significantly higher in the IBD patients as compared to controls. CONCLUSIONS The social support for children with IBD is excellent in this cohort. Only physical well-being was impaired due to disease activity, whereas all other KIDSCREEN parameters were better as compared to controls. This indicates that effective coping and support strategies may be able to compensate the burden of disease in pediatric IBD patients.

Abstract
BACKGROUND Appendiceal orifice inflammation (AOI) is a common 'skip lesion' in patients with ulcerative colitis (UC). However, other skip lesions are less well known. OBJECTIVE To evaluate the atypical distribution of UC lesions, other than AOI, in terms of their frequency, pattern, risk factors and prognostic implications. METHODS A retrospective analysis of colonoscopic findings and clinical course of 240 adult UC patients who were initially diagnosed at Asan Medical Center (Seoul, South Korea) was performed. # RESULTS Of 240 patients, 46 (19.2%) showed an atypical distribution of lesions at initial colonoscopy: eight (3.3%) had rectal sparing (segmental-type UC); and 38 (15.8%) had patchy⁄segmental skip lesions other than AOI. Skip lesions were detected more frequently in proximal segments of the colon than in distal segments (P=0.001). An atypical distribution was more common in patients with AOI (31.3%) than in those without AOI (10.6%; P<0.001). The clinical course of patients with an atypical distribution was not different from that of patients with a typical distribution in terms of remission, relapse, disease extension, colectomy and mortality. In addition, of the 36 patients with an atypical distribution of lesions at diagnosis who underwent follow-up colonoscopy, 24 (66.7%) demonstrated a typical distribution of lesions. CONCLUSIONS Patchy⁄segmental skip lesions and rectal sparing occur not infrequently in adult patients with newly diagnosed, untreated UC. As such, these features alone should not be considered to be definitive evidence against a diagnosis of UC. There does not appear to be a prognostic implication of an atypical distribution of lesions.

Abstract
Although the significance of focally enhanced gastritis (FEG) as a marker of Crohn disease (CD) in adults has been contested, several studies suggest that it may be more specific of CD in pediatric patients. This study describes the detailed histologic features of FEG in pediatric inflammatory bowel disease (IBD) and clarifies its association with CD. A series of 119 consecutive newly diagnosed IBD patients (62 CD cases, 57 ulcerative colitis [UC] cases) with upper and lower gastrointestinal biopsies were evaluated. The histology of the gastric biopsies was reviewed blinded to final diagnoses and compared with age-matched healthy controls (n=66). FEG was present in 43% of IBD patients (CD 55% vs. UC 30%, P=0.0092) and in 5% of controls. Among CD patients, FEG was more common in younger patients (73% in children aged 10 y and below, 43% in children above 10 y of age, P=0.0358), with the peak in the 5- to 10-year age group (80%). The total number of glands involved in each FEG focus was higher in UC (6.4±5.1 glands) than in CD (4.0±3.0 glands, P=0.0409). Amongst the CD cohort, patients with FEG were more likely than those without FEG to have active ileitis (79% vs. 40%, P=0.0128) and granulomas elsewhere in the gastrointestinal tract (82% vs. 43%, P=0.0016). There was no correlation between FEG and other gastrointestinal findings of UC. We demonstrate that differences in FEG seen in pediatric CD and UC relate to not only their frequencies but also the morphology and relationship with other gastrointestinal lesions. Further, FEG is associated with disease activity and the presence of granulomas in pediatric CD.

Abstract
UNLABELLED Clinical variables and disease course of pediatric ulcerative colitis (UC) have been poorly reported. The aim of this study was to retrospectively describe the phenotype and disease course of pediatric onset UC diagnosed at a tertiary referral Center for Pediatric Gastroenterology. PATIENTS AND METHODS 110 patients with a diagnosis of UC were identified at our Department database. Records were reviewed for disease location and behavior at the diagnosis, family history for inflammatory bowel disease, pattern changes at the follow-up, need of surgery and cumulative risk for colectomy. RESULTS Thirty-five % of patients had an early-onset disease (0-7 years). At the diagnosis, 29% had proctitis, 22% left-sided colitis, 15% extensive colitis and 34% pancolitis. Fifteen % presented with a rectal sparing, while a patchy colonic inflammation was reported in 18%. Rectal sparing was significantly related to the younger age (p: <0.05). Disease extension at the follow up was reported in 29% of pts. No clinical variables at the diagnosis were related to the subsequent extension of the disease. The cumulative rates of colectomy were 9% at 2 year and 14% at 5 years. An extensive disease as well as acute severe colitis and corticosteroid therapy at the diagnosis were significantly associated with an increased risk of colectomy. CONCLUSIONS Pediatric UC is extensive and severe at the diagnosis, with an overall high rate of disease extension at the follow-up. Endoscopic atypical features are common in young children. The colectomy rate is related to the location and severity of the disease at the diagnosis.

Abstract
The interpretation of colorectal biopsies taken for the initial diagnosis of chronic idiopathic inflammatory bowel disease (IBD) is challenging. Subclassification of IBD as ulcerative colitis (UC) or Crohn's disease, which may be particularly difficult, is the subject of this review. Biopsies taken at first presentation are emphasised, partly because their features have not been modified by time or treatment. Aspects of longstanding disease and of resections are also mentioned. The first part of the review comprises background considerations and a summary of histological features that are discriminant, according to published evidence, between UC and Crohn's disease in initial biopsies. Pitfalls and problems associated with making the distinction between UC and Crohn's disease are then discussed. These include: mimics of IBD; inadequate clinical details; unreliable microscopic features; absence of histological changes in early IBD; discontinuity in UC; cryptolytic granulomas; differences between paediatric and adult UC; reliance on ileal and oesophagogastroduodenal histology; and atypical features in IBD resections. Avoidance by pathologists of known pitfalls should increase the likelihood of accurate and confident subclassification of IBD, which is important for optimum medical and surgical management.

Abstract
The histologic examination of endoscopic biopsies or resection specimens remains a key step in the work-up of affected inflammatory bowel disease (IBD) patients and can be used for diagnosis and differential diagnosis, particularly in the differentiation of UC from CD and other non-IBD related colitides. The introduction of new treatment strategies in inflammatory bowel disease (IBD) interfering with the patients' immune system may result in mucosal healing, making the pathologists aware of the impact of treatment upon diagnostic features. The European Crohn's and Colitis Organisation (ECCO) and the European Society of Pathology (ESP) jointly elaborated a consensus to establish standards for histopathology diagnosis in IBD. The consensus endeavors to address: (i) procedures required for a proper diagnosis, (ii) features which can be used for the analysis of endoscopic biopsies, (iii) features which can be used for the analysis of surgical samples, (iv) criteria for diagnosis and differential diagnosis, and (v) special situations including those inherent to therapy. Questions that were addressed include: how many features should be present for a firm diagnosis? What is the role of histology in patient management, including search for dysplasia? Which features if any, can be used for assessment of disease activity? The statements and general recommendations of this consensus are based on the highest level of evidence available, but significant gaps remain in certain areas.

Abstract
No single test is diagnostic of Crohn's disease (CD). In the presence of a compatible clinical presentation, diagnosis is by convention confirmed by a combination of imaging, serologic, endoscopic and histologic investigations. This diagnostic recommendation should be maintained, even though histology is often 'compatible with' rather than 'diagnostic of' suspected CD. The importance of histology varies depending on the specific sites of macroscopic disease. Histology is particularly important in distinguishing type of inflammatory bowel disease, when the colon predominantly is involved, and in confirming CD when macroscopic disease is atypically located.

Abstract
Accurate histopathological assessment of biopsies is important for the diagnosis, subclassification, and management of chronic idiopathic inflammatory bowel disease (IBD). British Society of Gastroenterology (BSG) guidelines for the initial histopathological diagnosis of IBD were published in 1997. Changes since then include: more widespread use of full colonoscopy; greater recognition of the effects of time and treatment; improved documentation of variations in anatomical distribution; better understanding of the mimics of IBD; significant progress in clinical management; and modifications of terminology. Accordingly, an update is required. These revised guidelines aim to optimise the quality and consistency of reporting of biopsies taken for the initial diagnosis of IBD by summarising the literature and making recommendations based on the available evidence. Advice from existing clinical guidelines is also taken into account. Among the subjects discussed are: distinguishing IBD from other colitides, particularly infective colitis; subclassification of IBD (as ulcerative colitis, Crohn's disease, or IBD unclassified); the discriminant value of granulomas; aspects of disease distribution, including discontinuity in ulcerative colitis; time-related changes; differences between paediatric and adult IBD; the role of ileal and upper gastrointestinal biopsies; differential diagnoses such as diverticular colitis and diversion proctocolitis; and dysplasia. The need to correlate the histological features with clinical and endoscopic findings is emphasised. An approach to the conclusion of an IBD biopsy report based on the acronym Pattern, Activity, Interpretation, Dysplasia (PAID) is suggested. The key recommendations are listed at the end of the document.

Abstract
In the clinical context of pediatric diarrheal illness, the interpretation of endoscopic mucosal biopsies varies significantly from that in adults. This review outlines these differences by first describing a host of diarrheal illnesses that are nearly exclusive to the pediatric age group. The final portion of this article describes salient pathologic differences between adult and pediatric idiopathic inflammatory bowel disease. The goal of this review is to provide a brief description of each disease process and focus on practical aspects of diagnosis that are applicable for pathologists working in general practice settings.

Abstract
BACKGROUND Definitive diagnosis of pediatric ulcerative colitis (UC) may be particularly challenging since isolated colitis with overlapping features is common in pediatric Crohn's disease (CD), while atypical phenotypes of UC are not uncommon. The Paris classification allows more accurate phenotyping of atypical inflammatory bowel disease (IBD) patients. Our aim was to identify the prevalence of atypical disease patterns in new-onset pediatric UC using the Paris classification. METHODS Information was collected from the EUROKIDS Registry, an inception cohort of untreated pediatric IBD patients undergoing evaluation at diagnosis. Patients with IBD-unclassified were excluded. Patients with isolated Crohn's colitis served as a control group. RESULTS Data from 898 pediatric patients (643 UC, 255 CD colitis) were included. Extensive or pancolitis was present in 77% of UC patients and macroscopic rectal sparing in 5%. Rectal sparing was inversely associated with age (mean age with rectal sparing 9.9 years vs. 11.8 without; P = 0.02). Upper gastrointestinal (UGI) involvement occurred in 4% of patients. Erosions in the stomach were present in 3.1% of children, but frank ulcerations in 0.4%; 0.8% of children had erosions or ulcerations limited to the esophagus or duodenum. The corresponding UGI involvement in Crohn's colitis was 22%. A cecal patch occurred in 2% of patients. CONCLUSIONS Extensive disease and rectal sparing are age-dependent phenotypes in pediatric UC. Rectal sparing, cecal patch, backwash ileitis, and gastric erosions are not uncommon at diagnosis, while gastric ulcerations and erosions in the duodenum or esophagus are. Recognition of atypical phenotypes in pediatric-onset UC is crucial to prevent misclassification of IBD.

Abstract
BACKGROUND AND AIMS Pediatric ulcerative colitis (UC) shares many features with adult-onset disease but there are some unique considerations; therefore, therapeutic approaches have to be adapted to these particular needs. We aimed to formulate guidelines for managing UC in children based on a systematic review (SR) of the literature and a robust consensus process. The present article is a product of a joint effort of the European Crohn's and Colitis Organization (ECCO) and the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN). METHODS A group of 27 experts in pediatric IBD participated in an iterative consensus process including 2 face-to-face meetings, following an open call to ESPGHAN and ECCO members. A list of 23 predefined questions were addressed by working subgroups based on a SR of the literature. RESULTS A total of 40 formal recommendations and 68 practice points were endorsed with a consensus rate of at least 89% regarding initial evaluation, how to monitor disease activity, the role of endoscopic evaluation, medical and surgical therapy, timing and choice of each medication, the role of combined therapy, and when to stop medications. A management flowchart, based on the Pediatric Ulcerative Colitis Activity Index (PUCAI), is presented. CONCLUSIONS These guidelines provide clinically useful points to guide the management of UC in children. Taken together, the recommendations offer a standardized protocol that allows effective, timely management and monitoring of the disease course, while acknowledging that each patient is unique.

Abstract
Collagenous and lymphocytic colitis are common causes of chronic watery diarrhea that are characterized by distinct histopathologic abnormalities without endoscopically visible lesions and are summarized as microscopic colitis. Several variants of microscopic colitis have been described, although their clinical significance still has to be defined. Preserved mucosal architecture is a histologic hallmark of microscopic colitis and distinguishes the disease from inflammatory bowel disease (IBD). In addition to architectural abnormalities, the diagnosis of IBD rests on characteristic inflammatory changes. Differential diagnosis of IBD mainly includes prolonged infection and diverticular disease-associated colitis, also known as segmental colitis associated with diverticulosis.
