A clinical, morphological and molecular study of 70 patients with gastrointestinal involvement in systemic mastocytosis. Sci Rep 2024; 14:702. [PMID: 38184670 PMCID: PMC10771518 DOI: 10.1038/s41598-023-49749-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Accepted: 12/12/2023] [Indexed: 01/08/2024] Open
Abstract
In 70 patients with KIT D816V positive systemic mastocytosis (SM) including 36 patients with advanced SM (AdvSM), we correlated the extent of reported mucosal mast cell ([m]MC) infiltration of the upper and/or lower gastrointestinal tract (UGIT, n = 63; LGIT, n = 64; both, n = 57) with symptoms and markers of MC burden/subtype. GI symptoms were reported by all patients (mean 2.1 number of symptoms). A strong mMC infiltration was identified in 24 patients (UGIT, 17/63, 27%; LGIT, 19/64, 30%). Concurrent involvement of UGIT and LGIT (n = 12) correlated with female gender (75%) and a higher symptom burden (mean 2.7) but not with MC burden or subtype. Significant differences between non-AdvSM and AdvSM were reported regarding food intolerance (54% vs. 17%), cramping (54% vs. 22%) and weight loss (0% vs. 64%). KIT D816V was identified in 54/56 (96%) available biopsies. In 46 patients, digital PCR revealed a correlation with low albumin levels (r = - 0.270, P = 0.069) and the KIT D816V VAF in peripheral blood (r = 0.317, P = 0.036) but not with the extent of mMC infiltration or markers of MC burden/subtype. Although MC mediator triggered GI symptoms have a substantial impact on the quality of life, correlation to objective disease parameters is lacking thus making its systematic assessment challenging.

Abstract
INTRODUCTION Eosinophilic gastrointestinal disorders beyond eosinophilic esophagitis (non-EoE EGIDs) are rare chronic inflammatory disorders of the gastrointestinal (GI) tract. Diagnosis is based on clinical symptoms and histologic findings of eosinophilic inflammation after exclusion of a secondary cause or systemic disease. Currently, no guidelines exist for the evaluation of non-EoE EGIDs. Therefore, the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) formed a task force group to provide consensus guidelines for childhood non-EoE EGIDs. METHODS The working group was composed of pediatric gastroenterologists, adult gastroenterologists, allergists/immunologists, and pathologists. An extensive electronic literature search of the MEDLINE, EMBASE, and Cochrane databases was conducted up to February 2022. General methodology was used in the formulation of recommendations according to the Appraisal of Guidelines for Research and Evaluation (AGREE) II and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to meet current standards of evidence assessment. RESULTS The guidelines provide information on the current concept of non-EoE EGIDs, disease pathogenesis, epidemiology, clinical manifestations, diagnostic and disease surveillance procedures, and current treatment options. Thirty-four statements based on available evidence and 41 recommendations based on expert opinion and best clinical practices were developed. CONCLUSION Non-EoE EGIDs literature is limited in scope and depth, making clear recommendations difficult. These consensus-based clinical practice guidelines are intended to assist clinicians caring for children affected by non-EoE EGIDs and to facilitate high-quality randomized controlled trials of various treatment modalities using standardized, uniform disease definitions.

Abstract
Mastocytosis is a rare disease characterized by clonal expansion and accumulation of mast cells (MC) in various organs. Mastocytosis results from an activating mutation of the KIT surface receptor leading to an increased proliferation of MC. There are significant differences between children and adult patients with mastocytosis. Children mainly present the cutaneous form, whereas adults more often exhibit the systemic form of mastocytosis. Patients with mastocytosis may be asymptomatic or affected by a variety of symptoms. Treatment is primarily supportive and aims at symptom control. New approved targeted therapies such as midostaurin and avapritinib changed the treatment paradigm in advanced forms of the disease, and next-generation inhibitors currently in clinical trials are expected in the near future.

Abstract
Gastrointestinal symptoms are prevalent in patients with systemic mastocytosis and contribute to morbidity. In indolent disease, the symptoms, which include heartburn, abdominal pain, and diarrhea, are largely due to release of mast cell mediators but may be due to other factors. A thorough evaluation that incorporates abdominal imaging and endoscopy with intestinal biopsy assists with diagnosis and management. Patients with advanced mastocytosis experience signs and symptoms of gastrointestinal dysfunction owing to the massive infiltration of clonal mast cells in the tissues. The gastrointestinal symptoms in systemic mastocytosis are treatable with a combination of therapies, including those directed at mast cells.

Abstract
Mastocytosis (MC) is a heterogeneous group of disorders characterised by abnormal growth, neoplastic proliferation and accumulation of mast cells. Approximately, 80% of patients with MC have evidence of skin involvement, while the rest may involve the gastrointestinal tract, liver, spleen or bone. Isolated gastrointestinal presentation of aggressive MC without bone marrow involvement and cutaneous symptoms is rare. Isolated MC with tumour cells infiltrating the ileum presenting with mechanical obstruction has not been reported in the literature to date. Here, we present a case of a patient in his late 50s who presented with malignant MC of the small bowel with obstruction in the emergency surgical outpatient department. The patient underwent surgical resection of the affected bowel. Histopathological examination along with immunohistochemistry revealed malignant MC. The further evaluation consisted of bone marrow biopsies, PET CT and other mutation analyses. However, the patient succumbed to death during the further course of treatment. The differential of MC must be kept in mind when there is the presence of abnormal hematopoietic cells in gastrointestinal biopsies even in the absence of cutaneous manifestations and bone marrow abnormalities.

Abstract
Systemic mastocytosis is a rare myeloproliferative disorder characterized by abnormal accumulation of mast cells in a variety of organs. When affecting the gastrointestinal tracts, it may manifest with steatorrhea, malabsorption, hepatomegaly, splenomegaly, portal hypertension, and ascites, among others. To our knowledge, only one case of systemic mastocytosis has been reported affecting the appendix. We present another case of a 47-year-old woman who was admitted for right-sided acute abdominal pain and found to have systemic mastocytosis in her appendectomy specimen as the first and only manifestation of her disease.

Abstract
Mast cells are residents of the tubular gastrointestinal (GI) tract, where they play an important role in host defence and other vital functions. Dysregulation of mast cells has been implicated in the pathogenesis of several neoplastic, inflammatory, and functional disorders, some of which may manifest with GI symptoms. Surgical pathologists must therefore confront when and how to evaluate GI biopsies for mast cells, and whether such decisions should be based on morphologic criteria, clinical context, or direct request from clinical colleagues. The pathologist's role in evaluation of mast cell infiltrates is best defined in the diagnosis of systemic mastocytosis, where the utility of morphologic assessment coupled with ancillary studies is well established. In contrast, in nonneoplastic mast cell disorders such as mast cell activation syndrome, irritable bowel syndrome, or so-called 'mastocytic enterocolitis', a role for histopathology, if any, is controversial. Despite this, pathologists have seen a sharp increase in requests for mast cell quantification in the latter setting, despite these requests not being supported by published evidence. Moreover, what constitutes a 'normal' number of mast cells in a luminal GI biopsy is not well established. As a result, there is considerable variation in how these requests are handled in practice. This review evaluates and summarizes the published evidence relating to mast cell evaluation in endoscopic GI biopsies in various clinical scenarios, with a goal of providing practical, evidence-based guidance for the surgical pathologist when approached with requests for mast cell quantification in GI biopsies.

Abstract
BACKGROUND Systemic mastocytosis (SM), a rare myeloid neoplasm, is defined as a clonal and neoplastic proliferation of mast cells in at least one extracutaneous organ(s). The pathologic diagnosis and treatment of SM are challenging. CASE PRESENTATION We presented a 44-year-old male patient who had endured abdomen discomfort for 4 years and diarrhea for 5 months. Colonoscopy and PET/CT found a protuberant lesion in the cecum with adjacent lymphadenopathy. Histopathology of the cecum biopsy showed diffuse infiltration of medium-sized round/oval cells in lamina propria with immunohistochemical expressions of CD45, CD117, CD25, CD68, CD123, CD56, CD4, and CD35, mimicking blastic plasmacytoid dendritic cell neoplasm. Sanger sequencing revealed missense mutation (D816V) in the exon 17 of KIT gene. Serum tryptase level was 38.56 ng/ml. No abnormality was found in skin examination and bone marrow biopsy. No primitive cells were observed in bone marrow smear and peripheral blood smear. The diagnosis of aggressive SM with intestinal tract involvement was established. The patient received avapritinib treatment at an initial dosage of 200 mg once daily and exhibited dramatic clinical improvement but memory impairment within 1 month. No recurrence was observed in 1-year follow-up at the adjusted avapritinib dose (75 mg once daily). CONCLUSIONS SM is very rare and should be considered in patients with long-term diarrhea symptoms and hematopoietic/lymphoid-appearing tumors. KIT D816V mutation contributes to the differentiation of CD123, CD4, and CD56 immunoreactive SM from blastic plasmacytoid dendritic cell neoplasm. The rare side-effect of memory impairment in this case helps to accumulate the experience of avapritinib in treating KIT D816V-mutant SM.

Abstract
Mastocytosis, or mast cell proliferation, is very rare. Overall, 60% of patients with systemic mastocytosis (SM) have gastrointestinal involvement, with the colon being the most prevalent affected site. Most patients are diagnosed by bone marrow biopsy. Although gastrointestinal symptoms are common, patients are rarely diagnosed via endoscopy. Indolent SM, which is characterized by both gastrointestinal and cutaneous symptoms in the absence of bone marrow suppression, is extremely rare and often missed due to the complexity of the diagnosis. Here, we present the case of a patient with abdominal pain, flushing, and nausea who was diagnosed endoscopically with SM, likely the indolent type.

Abstract
Mastocytosis is a rare and heterogeneous disease characterized by various clinical and biological features that affect different prognoses and treatments. The disease is usually divided into 2 principal categories: cutaneous and systemic disease (SM). Clinical features can be related to mast cell (MC) mediator release or pathological MC infiltration. SM is a disease often hard to identify, and the diagnosis is based on clinical, biological, histological, and molecular criteria with different specialists involved in the patient’s clinical work-up. Among all manifestations of the disease, gastrointestinal (GI) symptoms are common, being present in 14%-85% of patients, and can significantly impair the quality of life. Here we review the data regarding GI involvement in SM, in terms of clinical presentations, histological and endoscopic features, the pathogenesis of GI symptoms, and their treatment.

Abstract
Introduction Systemic mastocytosis is a rare disease resulting from infiltration of atypical mast cells in multiple organ systems and present with variety of symptoms. Primary appendiceal and cecal mass with isolated abdominal pain as a presenting feature in systemic mastocytosis have not been reported in literature up to now. Case report We described a 69- years-old female with systemic mastocytosis who presented with chronic abdominal pain and recent progression. On imaging of the abdomen and pelvis showed a mass in cecum. The patient underwent surgery and histopathologic evaluation of cecal and appendiceal masses revealed uniform small round cell tumor with eosinophilic cytoplasm admixed with many eosinophils distorting normal colonic mucosal architecture. The neoplastic cells showed positive expression of CD117 and Mast cell tryptase. According to all these considerations systemic mastocytosis was confirmed as the diagnosis. Conclusion Isolated abdominal pain and primary large intestinal mass are uncommon features of systemic mastocytosis. This case report informed physicians and pathologists to consider it as one of differential diagnosis. Mastocytosis is an uncommon neoplastic infiltration of mast cells in one or multiple organs. Isolated abdominal pain and primary large intestinal mass are uncommon features of systemic mastocytosis. Mastocytosis reveal common surprising clinical signs that to conclude lead to inadequate treatment. mastocytosis.

Systemic mastocytosis (SM) is a myeloid neoplasm characterized by abnormal growth and accumulation of neoplastic mast cells in at least one extracutaneous site. Clinical presentation and course are variable, most patients developing an indolent disease and some, an aggressive/leukemic form. Because of its rarity, most physicians are unfamiliar with this disease and do not readily diagnose it. In the present retrospective study, the authors describe 12 patients diagnosed with mast cell neoplasm. Cases were selected from three institutions from Campinas and São Paulo City, Brazil. Morphological features and diagnostic pitfalls are emphasized. Patients' age ranged from 15 to 81 years (mean 51.6 years). Male and female were affected similarly (1:1). Ten patients were classified as aggressive systemic mastocytosis (SM), one patient as SM with an associated acute promyelocytic leukemia with t(15;17), and one patient with mast cell sarcoma. Most common clinical findings included anemia (9 patients), thrombocytopenia (3 patients) and skin lesions (3 patients). Bone marrow was involved in 11 patients at diagnosis, followed by skin (5 patients). Five morphological patterns were present: mast cell aggregates (5), plasmacytoid (4), monocytoid (2), spindle cell (2) and epithelioid/pleomorphic (1); two patients showed two histological patterns. In all cases neoplastic cells were positive for CD117/C-KIT. C-KIT D816V mutation was present in four patients, C-KIT K509I in two, and del(7q22) in one; in five cases no mutational status was available. Despite limited resources, basically morphology and a restricted immunohistochemical panel, it is possible to diagnose mast cell neoplasm. Of note, pathologist should recognize the different morphological variants of the disease and include the adequate markers when requesting immunohistochemical studies.

Abstract
Systemic mastocytosis (SM) is a heterogeneous disease that often involves the gastrointestinal (GI) tract. Activation and accumulation of mast cells in GI organs can result in symptoms of abdominal pain, nausea and diarrhea along with organ damage with more aggressive disease. Mast cell degranulation can also result in anaphylactic reactions, which can be life-threatening. Recognition of GI manifestations is important for gastroenterologists to aid in diagnosis and management when GI involvement is suspected. Edema, small nodules, urticarial lesions and occasionally ulceration in the small bowel and colon are the most commonly described endoscopic findings. Here we describe a case of SM presenting as a large colonic mass and provide a brief review of the literature on GI involvement of SM.

Abstract
Simple Summary Mastocytosis is a group of neoplastic mast cell disorders ranging from a skin-limited disease to a systemic form with multi-organ involvement, including gut involvement. Clinical manifestations and outcome of systemic mastocytosis are variable. Symptoms may result from either release of mast cell mediators or tissue infiltration by mast cell proliferation. Gastrointestinal symptoms are one of the major causes of morbidity in these patients. The diagnosis of gastrointestinal mastocytosis can be tricky, as symptoms often mimic other more common gastrointestinal diseases; the endoscopic appearance is often unremarkable or nonspecific and the infiltrate can be focal and subtle and easily missed unless special stains are used. This review aims to better define the gastrointestinal involvement in systemic mastocytosis, discussing potential diagnostic pitfalls and pointing out the importance of a multidisciplinary approach for a prompt diagnosis and treatment. Abstract Mastocytosis represents a heterogeneous group of neoplastic mast cell disorders. The basic classification into a skin-limited disease and a systemic form with multi-organ involvement remains valid. Systemic mastocytosis is a disease often hard to diagnose, characterized by different symptoms originating from either the release of mast cell mediators or organ damage due to mast cell infiltration. Gastrointestinal symptoms represent one of the major causes of morbidity, being present in 60–80% of patients. A high index of suspicion by clinicians and pathologists is required to reach the diagnosis. Gastrointestinal mastocytosis can be a challenging diagnosis, as symptoms simulate other more common gastrointestinal diseases. The endoscopic appearance is generally unremarkable or nonspecific and gastrointestinal mast cell infiltration can be focal and subtle, requiring an adequate sampling with multiple biopsies by the endoscopists. Special stains, such as CD117, tryptase, and CD25, should be performed in order not to miss the gastrointestinal mast cell infiltrate. A proper patient’s workup requires a multidisciplinary approach including gastroenterologists, endoscopists, hematologists, oncologists, and pathologists. The aim of this review is to analyze the clinicopathological features of gastrointestinal involvement in systemic mastocytosis, focusing on the relevance of a multidisciplinary approach.

Abstract
Mastocytosis is a rare and heterogeneous group of disorders that may be limited to the skin and even spontaneously regress or may have a systemic presentation with multi-organ involvement and poor outcome. Among the extracutaneous sites, gastrointestinal tract is often affected, but nonspecific clinical manifestations combined with subtle histological findings of the disease makes the diagnosis of gastrointestinal mastocytosis rather hard. In absence of a high index of suspicion, gastrointestinal involvement is easily overlooked. We report a challenging case of systemic mastocytosis presenting with isolated gastrointestinal manifestations without skin involvement, in which the diagnosis was missed at first evaluation of intestinal biopsies.

Abstract
Eosinophilic gastrointestinal disorders (EGID) are characterized pathologically by excess eosinophils in mucosal biopsies of one or multiple sites in the gastrointestinal (GI) tract, simultaneously or sequentially. Eosinophilic esophagitis (EoE) is the best characterized EGID, and in most patients it is an abnormal immune-mediated response to food antigens. Current recommendations for diagnosis include signs and symptoms of esophageal dysfunction that do not respond to proton-pump inhibitor therapy, and esophageal biopsies that exhibit at least 15 intraepithelial eosinophils in at least one high power field (HPF). Therapy consists of swallowed glucocorticoids or dietary elimination. Eosinophilic gastritis (EG) is the second most common form of EGID, but like all forms of EGID except EoE consensus recommendations for either clinical or pathological diagnosis do not exist. EG may be associated clinically with peripheral blood eosinophilia, hypoalbuminemia, and anemia, and pathologically with marked expansion of lamina propria by dense eosinophilic infiltrates. Eosinophilic enteritis (EE) may be subdivided into eosinophilic duodenitis, eosinophilic jejunitis, and eosinophilic ileitis. Most investigators believe that EE rarely, if ever, exists as a solitary form of EGID and is encountered only in patients who have at least one other affected portion of the GI tract. Eosinophilic colitis (EC) is perhaps the most enigmatic EGID. Distinction of EC from inflammatory bowel disease may be problematic especially in children. Multiple possible etiologies for EGID include hypereosinophilic syndrome, drug reactions, etc. Currently, the only etiology that can be identified histologically is parasitic infestation, if a portion of an invasive parasite is found in mucosal biopsies. This review will provide guidelines for the pathologic diagnosis of the various forms of EGID.

Abstract
In 5 Japanese Black steers (2-2.4 years old) that originated from 5 different feedlots, the livers were found at slaughter to have multiple nodular or cordlike lesions (5 steers) and an extensive fibrotic area (1 steer). Microscopic changes included extensive fibroplasia in the portal tracts and chronic proliferative endophlebitis-like lesions confined to the portal vein branches. Fibroplasia was much more prominent in the macroscopic fibrotic lesion of 1 steer. Portal vein branches presented irregular variciform dilation of the vascular lumen and fibroplastic changes in the subendothelial areas that showed occasional hemorrhage and were simultaneously infiltrated with large numbers of mast cells and moderate to large numbers of eosinophils. Within these subendothelial regions, not only did mast cells exhibit cytologically atypical features, but they also formed multifocal nodules. The venous lesions may represent a variant of mastocytosis with specific involvement of the hepatic portal vein branches in cattle.

Abstract
Zoledronic acid (ZA), an intravenous aminobisphosphonate, is prescribed widely for postmenopausal osteoporosis. It is a relatively safe drug but may cause adverse effects including acute phase reaction. Oral non-aminobisphosphonates are known to cause diarrhoea that is usually mild and self-limited. Intravenous amino-bisphosphonates are not known to cause diarrhoea. We describe a case of acute watery diarrhoea complicated by severe hyponatremia and hypotension following ZA infusion. The patient needed intensive care for four days. To the best of our knowledge, this type of acute diarrhoea complicated by severe hyponatremia, following ZA infusion, is not reported so far. Strong temporal relation with ZA administration makes it the most likely cause. Furthermore, all laboratory and imaging parameters indicate that the secretory diarrhoea may be a component of acute phase reaction. According to World Health Organization (WHO) causality scale, ZA was a probable cause of acute watery diarrhoea in our patient. Clinicians should be aware that ZA administration can cause acute watery diarrhoea and may lead to severe hypotension and hyponatremia.

Abstract
Mastocytosis is a clonal neoplastic disorder of the mast cells (MC) that can be limited to the skin (cutaneous mastocytosis) or involve one or more extracutaneous organs (systemic mastocytosis). The clinical manifestations of mastocytosis are heterogeneous ranging from indolent disease with a long-term survival to a highly aggressive neoplasm with survival of about 6 mo. Although liver involvement in aggressive systemic mastocytosis (ASM) is relatively common, the development of portal hypertension with or without cirrhosis is rare. We report a case of ASM without skin involvement in a 72-year-old caucasian male who presented with non-cirrhotic portal hypertension based on clinical, analytical, imagiological and endoscopic findings. Given the hematological picture, the correct diagnosis was established based on ancillary tests for MC using bone marrow aspirates and biopsy. Extensive involvement of the liver and gastrointestinal tract was histologically documented. The disease progressed rapidly and severe pancytopenia and recurrent upper gastrointestinal bleeding became the dominant problem. This case illustrates the challenge in establishing a diagnosis of ASM especially when the clinical picture is atypical and without skin involvement. Gastroenterologists should consider infiltrative disease, particularly systemic mastocytosis, as a differential diagnosis in a clinical case of portal hypertension of unknown etiology.

Abstract
Counting mast cells in gastrointestinal (GI) mucosal biopsies is becoming an increasingly common practice. The primary reason for this exercise is to evaluate for possible involvement by systemic mastocytosis (SM). However, the features of mastocytosis in GI biopsies are not well described. In addition, recent studies have suggested that increased mast cells may be involved in the pathogenesis of some cases of diarrhea-predominant irritable bowel syndrome (IBS); the term "mastocytic enterocolitis" has been proposed for such cases. As the baseline mast cell density in colonic biopsies from normal patients has not been established in large cohorts, there is no widely accepted threshold for what constitutes increased mucosal mast cells. The aims of this study were (1) to determine the utility of GI biopsies for the diagnosis of SM, (2) to characterize the clinical, histologic, and immunohistochemical features of mastocytosis in the GI tract, (3) to determine mast cell density in normal colonic mucosa from a large cohort of asymptomatic patients, and (4) to compare these findings with those from patients with diarrhea-predominant IBS. Twenty-four patients with SM involving the GI tract, 100 asymptomatic patients, and 100 patients with IBS (the latter 2 groups with histologically normal colonic biopsies) were included. For the mastocytosis group, 107 biopsies (70 involved by mastocytosis; 67 mucosal, 3 liver) from 20 women and 4 men were evaluated (median age 59 y). The most commonly involved site was the colon (19 patients, 95%), followed by ileum (86%), duodenum (80%), and stomach (54%). In 16 cases (67%), the first diagnosis of SM was made on the basis of GI biopsies. Seventeen patients had documented cutaneous mastocytosis. Fifteen of 17 patients who underwent bone marrow biopsy had marrow involvement by SM. Eighteen patients had indolent disease, and 6 had aggressive disease (including all 3 with liver involvement). The most common GI symptom was diarrhea, followed by abdominal pain, nausea, weight loss, bloating, vomiting, or reflux. Liver disease presented with hepatomegaly and ascites. Endoscopic abnormalities (observed in 62%) included erythema, granularity, and nodules. Histologically, involved biopsies were characterized by infiltrates of ovoid to spindle-shaped mast cells in aggregates or sheets in the lamina propria, sometimes forming a confluent band underneath the surface epithelium; 25% of biopsies had only focal involvement (single aggregate). Prominent eosinophils were seen in 44% of involved colonic/ileal biopsies and 16% of duodenal biopsies. Mast cells were highlighted by diffuse membranous staining for KIT and CD25. In the nonmastocytosis groups, all biopsies contained singly dispersed mast cells with no aggregates. The mean highest mast cell counts (in a single high-power field) for asymptomatic patients and IBS patients were 26 (range, 11 to 55) and 30 (range, 13 to 59), respectively. In summary, GI (especially colonic) biopsies can establish a diagnosis of SM in patients with GI symptoms. GI involvement is usually subtle and is often associated with prominent eosinophils, which may obscure the mast cell infiltrate. KIT and CD25 are invaluable markers for the diagnosis. Mast cell density in colonic mucosa from asymptomatic patients is highly variable. Although patients with diarrhea-predominant IBS on average have mildly increased mast cells, the overlap in range with that of control patients is too great for this difference to be clinically useful. These findings argue against the utility of counting GI mucosal mast cell in patients with chronic diarrhea.

Abstract
BACKGROUND Mastocytosis is a heterogeneous disease characterized by mast cell accumulation in 1 or more organs. Gastrointestinal manifestations of systemic mastocytosis have been previously studied in small cohorts of patients, and no specific histologic description is available. OBJECTIVE We sought to assess the clinical and pathologic features of gastrointestinal manifestations in patients with mastocytosis. METHODS Medical history and gastrointestinal symptoms of patients with mastocytosis (n = 83) were compared with those of matched healthy subjects (n = 83) by means of patient questionnaire. Data were analyzed for epidemiologic, clinical, biological, and genetic factors associated with gastrointestinal symptoms for patients with mastocytosis. A comparative analysis of gastrointestinal histology from patients with mastocytosis (n = 23), control subjects with inflammatory bowel disease (n = 17), and healthy subjects (n = 19) was performed. RESULTS The following gastrointestinal symptoms occurred more frequently and were more severe in patients with mastocytosis than in healthy subjects: bloating (33% vs 7.2%, P < .0001), abdominal pain (27.3% vs 4.8%, P < .0001), nausea (23% vs 8.4%, P = .02), and diarrhea (33.85% vs 1.2%, P < .0001). Patients with mastocytosis had a significantly higher incidence of personal history of duodenal ulcer (P = .02). Wild-type (WT) c-Kit was associated with diarrhea (P = .03). Specific histologic lesions were present in patients with mastocytosis but were not correlated with clinical symptoms. CONCLUSION Gastrointestinal manifestations in patients with mastocytosis are highly prevalent and often severe. Clinical symptoms do not correspond to histologic findings, are nonspecific, and can simulate irritable bowel syndrome.

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.

Abstract
A 53 year old woman presented with abnormal liver function tests and subsequently developed intermittent abdominal pain, vomiting and diarrhoea. There were no rash or anaphylactoid reactions. Endoscopic biopsies showed excessive density of eosinophils and immunohistochemical staining for tryptase revealed a florid mast cell infiltrate. A diagnosis of systemic mastocytosis was made by bone marrow biopsy. Systemic mastocytosis is a rare myeloid neoplasm often associated with gastrointestinal symptoms due usually to mediator release but may rarely represent organ infiltration. While endoscopic and routine biopsy appearances are non-specific, suggestive features should lead to staining for mast cell tryptase or CD 117. However, diagnose generally requires bone marrow biopsy. The prognosis in the majority of patients is good and supportive management only is required. For patients with aggressive disease, cytoreductive therapy may be needed.

Abstract
Eosinophils, a constitutive component of the columnar-lined gastrointestinal tract, play an essential role in allergic responses and parasitic infections. The tissue density of these cells also increases in a variety of conditions of uncertain etiology. With the exception of the esophageal squamous epithelium, in which no eosinophils are normally present, the population of normal eosinophils in the remainder of the luminal gut is poorly defined. Therefore, histopathologists must rely on their subjective judgment to determine when a diagnosis of eosinophilic gastritis, enteritis, or colitis should be rendered. Eosinophilic esophagitis is currently the best defined and most studied eosinophilic condition of the digestive tract; therefore, the confidence in accurate diagnosis is increasing. In contrast, the characteristic clinicopathologic features of eosinophilic conditions affecting other parts of the digestive tract remain somewhat elusive. This review was designed to present pathologists with simple and practical information for the biopsy-based histopathologic diagnosis of eosinophilic esophagitis, gastritis, enteritis, and colitis. It was prepared by critically reviewing more than 200 articles on the topic, along with incorporating evidence accumulated through our own collective experience. We anticipate that by increasing pathologists' confidence in reporting these abnormal but often nameless eosinophilic infiltrates, we can help better define and characterize their significance.

Abstract
Mastocytosis is a rare and heterogeneous disease characterized by various biological and clinical features with different prognosis and treatments. The disease is usually divided into 2 categories: a pure cutaneous and a systemic disease. Clinical features can be related to mast cells' mediators release or to pathological mast cells infiltration. The diagnosis of mastocytosis is based on clinical, biological, histological, and molecular international criteria. Among all manifestations of the disease, gastrointestinal (GI) symptoms are common and can significantly impair the quality of life. The aim of this article is to review the data regarding GI involvement in mastocytosis. Articles dealing with clinical, pathophysiological, and therapeutic aspects of mastocytosis GI tract involvement were searched for using PubMed. GI manifestations in mastocytosis are reviewed. Pathogenesis of GI symptoms in systemic mastocytosis and their treatment are critically discussed. The most frequent GI symptoms are abdominal pain, diarrhea, nausea, and vomiting. GI lesions may involve all the digestive tract, from the esophagus to the rectum. The histological diagnosis of GI involvement is difficult. The treatment of GI symptoms aims to prevent and limit mast cells degranulation and/or its consequences and more rarely to control tumoral mast cells infiltration. The high prevalence of GI symptoms in mastocytosis and their important functional impact deserves better characterization and treatment in order to improve patients' quality of life. Diagnosis of mastocytosis GI manifestations should be evoked in the case of unexplained severe GI disorders.

Abstract
Mastocytosis refers to a heterogeneous group of rare disorders characterized by an abnormal accumulation of mast cells in one or more organ systems. Cutaneous mastocytosis (CM) is the most frequent form in children and is characterized by hyperpigmented macules or papules symmetrically distributed over the trunk, and less so over the limbs, neck, and scalp. Two published articles have reported on unrelated girls presenting with mastocytosis, microcephaly, hearing loss, and hypotonia. Based on the original observation, this disorder was defined as CM with short stature, conductive hearing loss, and microtia (OMIM 248910). Here we report on a girl with similar manifestations who corroborates the existence of this rare disorder. CM, microcephaly, microtia, and/or hearing loss are the minimal diagnostic criteria. All the known patients were sporadic, but parental consanguinity in the first case argues for a possible autosomal-recessive inheritance.
