Abstract
OBJECTIVE To evaluate the prognostic value of T1 substaging in patients treated with bacillus Calmette-Guérin (BCG) or immediate radical cystectomy (iRC). MATERIALS AND METHODS We performed an institutional review board-approved retrospective study analysing non-muscle-invasive bladder cancer (NMIBC) patients with pT1 disease treated with either BCG or iRC between 2000 and 2020. Lamina propria (LP) invasion characteristics were extracted from the pathology report. The Kaplan-Meier method was used to calculate overall survival (OS), cancer-specific survival (CSS) and metastasis-free survival (MFS). Multivariable Cox models were used to determine the association between progression-free survival (PFS) and characteristics in the BCG cohort. A logistic regression model explored the relationship between T1 substaging and upstaging to >pT2 at iRC. RESULTS A total of 411 T1 high-grade patients were identified. LP invasion characteristics were as follows: not specified: 115 (28%); focal/superficial (F/S): 147 (35.8%); and extensive/multifocal (E/M): 149 (36.2%). Overall, 303 patients (73.7%) received BCG, and 108 patients (26.3%) underwent iRC. The median (interquartile range) follow-up was 53 (32-96) months. Patients with E/M LP invasion were significantly more likely to undergo iRC (34% vs. 19%; P = 0.003). Patients with E/M LP invasion showed poorer MFS and CSS compared to those with F/S LP invasion when treated with BCG but not when treated with iRC. Among BCG-treated patients, progression occurred in 41 patients and E/M LP invasion was independently associated with progression after BCG (hazard ratio 5.3, 95% confidence interval [CI] 2.2-13.1; P < 0.001). T1 substaging was not associated with upstaging at RC (odds ratio 3.15, 95% CI 0.82-12.12; P = 0.095). CONCLUSIONS Extensive/multifocal LP invasion was associated with poor PFS, MFS and CSS in patients treated with BCG. T1 substaging provides valuable prognostic information and should be reported in pathology reports.

Abstract
BACKGROUND Gallbladder cancer (GBC) is the most common biliary tract malignancy and has a poor prognosis. The clinical significance of focal vs diffuse GBC remains unclear. METHODS A retrospective review was conducted on all patients with non-metastatic GBC at a quaternary care center. Pathology was reviewed, and gallbladder cancer pattern was defined based on the extent of mucosal involvement; "diffuse" if the tumor was multicentric or "focal" if the tumor was only in a single location. Patients undergoing liver resection and portal lymphadenectomy were considered to have definitive surgery. The primary outcome was overall survival and assessed by Kaplan-Meier curves. RESULTS 63 patients met study criteria with 32 (50.7%) having diffuse cancer. No difference was observed in utilization of definitive surgery between the groups (14 [43.8%] with focal and 12 [38.7%] with diffuse, P = .88). Lymphovascular invasion (P = .04) and higher nodal stage (P = .04) were more common with diffuse GBC. Median overall survival was significantly improved in those with focal cancer (5.1 vs 1.2 years, P = .02). Although not statistically significant, this difference in overall survival persisted in patients who underwent definitive surgery (4.3 vs 2.4 years, P = .70). DISCUSSION Patients with diffuse involvement of the gallbladder mucosa likely represent a subset with aggressive biology and worse overall survival compared to focal disease. These findings may aid surgeons in subsequent surgical and medical decision-making for patients with GBC.

Abstract
BACKGROUND/AIM Epitope H contains an O-linked N-acetylglucosamine (O-GlcNAcH) residue in a specific conformation or environment, recognized by a site-specific monoclonal mouse IgM antibody H. O-GlcNAcH occurs in several normal and pathological cells and in several polypeptides, including keratin-8 and vimentin, on the latter in cells under stress. MATERIALS AND METHODS In this work, we studied the distribution of O-GlcNAcH on cells of endocervical mucosa in 60 specimens of endocervical curettings, 10 of which contained 15 inflamed polyps. RESULTS In our results, expression of O-GlcNAcH was weak in the mucosa with <5% mucin-secreting cells and up to 30% of the polyps staining positively. All non-ciliated, non-mucin-secreting cells, normal and hyperplastic 'reserve' cells, as well as the cells of immature squamous metaplasia, showed strong diffuse cytoplasmic staining for O-GlcNAcH. In mature squamous epithelium, fewer than 5% of basal cells and all the intermediate and superficial cells showed cytoplasmic staining for O-GlcNAcH, whereas parabasal cells were negative. All ciliated cells showed patchy or diffuse cytoplasmic staining. Nuclear staining for O-GlcNAcH was weak with fewer than 5% of hyperplastic 'reserve' and ciliated cells staining positively. Moreover, mucosal fibroblasts were negative, whereas all stromal cells of the polyps showed strong cytoplasmic staining for O-GlcNAcH. CONCLUSION O-GlcNAcH is: a) differentially expressed among the cellular elements of mucosa and polyps, b) upregulated in mucin-secreting cells of polyps, c) induced in stromal cells of inflamed polyps, and d) can be used as a marker to differentiate between 'reserve' (positive) and parabasal (negative) cells, which have similar morphology using conventional cytological stains.

Abstract
Background Lichen planus pemphigoides (LPP), an association between lichen planus and bullous pemphigoid lesions, is a rare subepithelial autoimmune bullous disease. Mucous membrane involvement has been reported previously; however, it has never been specifically studied. Methods We report on 12 cases of LPP with predominant or exclusive mucous membrane involvement. The diagnosis of LPP was based on the presence of lichenoid infiltrates in histology and immune deposits in the basement membrane zone in direct immunofluorescence and/or immunoelectron microscopy. Our systematic review of the literature, performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, highlights the clinical and immunological characteristics of LPP, with or without mucous membrane involvement. Results Corticosteroids are the most frequently used treatment, with better outcomes in LPP with skin involvement alone than in that with mucous membrane involvement. Our results suggest that immunomodulators represent an alternative first-line treatment for patients with predominant mucous membrane involvement.

Abstract
OBJECTIVES It is thought that esophageal hypersensitivity in combination with an impaired mucosal barrier function contributes to PPI-resistant reflux symptoms. Ziverel, a bioadhesive agent that coats the esophageal wall, was shown to have a positive effect on reflux symptoms. However, the mechanisms of action are unclear. We aimed to assess the effect of Ziverel on esophageal sensitivity to acid and mucosal barrier function. METHODS We performed a double-blind randomized placebo-controlled crossover trial in PPI-refractory patients with reflux symptoms. Patients were assigned (1:1) to 14 days of Ziverel followed by 14 days of placebo or opposite treatment order. The effect was evaluated using acid perfusion tests, an upper endoscopy with electrical tissue impedance spectroscopy (ETIS) and esophageal biopsies. The primary outcome was the esophageal sensitivity based on perfusion sensitivity score. Secondary outcomes included mucosal barrier function and reflux symptoms and correlations between the different outcomes. RESULTS Perfusion sensitivity score was not significantly different during treatment with Ziverel (106 (73-115)) and placebo (102 (67-110)) (p = 0.508) along with total RDQ score (2.6 (1.9-3.3) vs 2.8 (1.6-3.5) p = 0.456). ETIS showed comparable values during treatment with Ziverel (13514 (8846-19734)Ω·m) and placebo (13217 (9127-24942)Ω·m (p = 0.650)). Comparing Ziverel and placebo no difference was seen in transepithelial electrical resistance (TEER) 203 (163-267) Ω.cm2 vs 205 (176-240) Ω.cm2 (p = 0.445) and fluorescein flux 775 (17-6964) nmol/cm2/h vs 187 (4-12209) nmol/cm2/h (p = 0.638). CONCLUSION Ziverel did not show a benefit on acid sensitivity, reflux symptoms or esophageal mucosal integrity compared to placebo in PPI-refractory patients with reflux symptoms.Trial registration: Netherlands Trial Register number: NL7670.

Abstract
Middle ear tumors are diverse, but relatively uncommon. The most frequent tumor in the middle ear is glomus tumor, followed by others such as schwannoma and cholesteatoma. We experienced a case of Mucosa-associated lymphoid tissue hyperplasia as a middle ear tumor. The mass behind tympanic membrane appeared a hypervascular tumor, mimicking a glomus tumor, but the form of multiple separate masses in middle ear and mastoid cavity was the distinguishing feature that set it apart from a glomus tumor. Additionally, another characteristic was its tendency to easily shrink under pressure. This characteristic should be considered when encounter a hypervascular looking middle ear mass.

Abstract
OBJECTIVES Dysbiosis of the sinonasal microbiome has been implicated in the pathogenesis of chronic rhinosinusitis (CRS). However, the mycobiome remains largely understudied, and microbial alterations associated with specific CRS subtypes have yet to be delineated. The objective of this study is to investigate the fungal and bacterial microbiome of sinus mucosa in CRS patients with and without nasal polyposis (CRSwNP and CRSsNP) versus healthy controls. METHODS Sinus mucosa was obtained from 92 patients (31 CRSsNP, 31 CRSwNP, and 30 controls) undergoing endoscopic sinus/skull base surgery. Data regarding demographics, Lund-MacKay scores, and histopathology were collected. Fungal and bacterial microbiome analysis was performed utilizing internal transcribed spacer amplicon and 16S rRNA sequencing. RESULTS Beta diversity of the sinonasal mycobiome differed significantly between CRS and controls (p = 0.001) and between CRSwNP and controls (p = 0.049), but not between CRSwNP and CRSsNP (p = 0.32) nor between CRSsNP and controls (p = 0.06). With respect to the bacterial microbiome, significantly lower alpha diversity was observed between CRS and controls (p < 0.001), CRSwNP versus controls (p < 0.001), and CRSsNP versus controls (p < 0.001). Beta diversity was also significantly different at the genus level between CRSwNP and CRSsNP (p = 0.019), CRSwNP and controls (p = 0.002)), and CRSsNP and controls (p < 0.001). However, alpha and beta diversity did not differ significantly between CRS patients with/without eosinophils or correlate with Lund-MacKay scores. CONCLUSIONS Differences in mycobiota diversity in CRS patients in comparison with controls suggest that alterations in the mycobiome may contribute to disease pathogenesis. Our findings also confirmed that diminished diversity among bacterial communities is associated with CRS and that significant differences are present in microbial composition between CRSwNP and CRSsNP.

Abstract
BACKGROUND Standard impedance catheters and balloon-based mucosal impedance catheters (BBMI) have been used to assess mucosal integrity and diagnose mucosal diseases. The goal of this study was to determine the age-related technical issues associated with mucosal balloon inflation, validate the BBMI measurement against a standard impedance probe, and compare software-generated diagnoses to histologic diagnoses. METHODS We prospectively recruited patients undergoing endoscopy, during which patients underwent standard mucosal impedance catheters and BBMI measurements. Measurements were compared to each other, to the histologic diagnoses, and to the number of eosinophils per high power field. We then compared the patients' diagnosis to that assigned by the BBMI software. KEY RESULTS Sixty-two patients (mean age: 62 ± 62 months) were recruited, including non-GERD (N = 40), GERD (N = 15), and EoE (N = 7) patients. There were significant differences between the impedance values measured by the two technologies at each esophageal height (p < 0.003). There were significant correlations between the mean impedance values taken by the two catheters in the distal (r2 = 0.272, p = 0.04), mid (r2 = 0.371, p < 0.001), and proximal (r2 = 0.259, p = 0.05) esophagus. There were significant differences in BBMI impedance values across diagnoses in the mid and proximal esophagus (p = 0.024 and 0.025, respectively). While not statistically significant (p = 0.061-0.073), the standard catheter showed similar trends by diagnosis. Using the BBMI diagnostic prediction software, 33%-72% of patients were misclassified. CONCLUSION AND INFERENCES While there was significant variability in impedance values between technologies within patients, regional measurements were consistent across catheters. Automated analyses lacked the sensitivity to diagnose inflammatory disorders.

Abstract
BACKGROUND L-Menthol sprayed on early gastric cancer (EGC) has been reported to improve the visibility of the lesion. However, its impact when used in combination with novel image-enhanced endoscopy has not been investigated. AIM This study aimed to evaluate the visual effect of spraying L-menthol on EGC under linked color imaging (LCI). METHODS This open-label, single-arm, prospective study investigated the color difference between EGC and the surrounding mucosa (ΔEG) before and after spraying L-menthol. The primary endpoint was the percentage of lesions with ΔEG ≥ 5 on LCI. The percentage of lesions with ΔEG ≥ 5 on white light imaging (WLI) and blue laser imaging (BLI), ΔEG before and after spraying L-menthol, and percentage of lesions with increased ΔEG after spraying L-menthol constituted the secondary endpoints. RESULTS Sixty patients were included in the final analysis. 100% lesions had ΔEG ≥ 5, both before and after spraying L-menthol on LCI, with similar results observed in WLI as well as BLI. The median ΔEG on LCI, WLI, and BLI increased after spraying L-menthol (LCI: 16.9 vs. 21.5, p < 0.01; WLI: 10.4 vs. 13.4, p < 0.01; BLI; 12.1 vs. 15.7, before and after, respectively, p < 0.01); and LCI demonstrated the highest percentage of lesions with increased ΔEG (LCI, WLI, and BLI: 98.3%, 81.7%, and 76.7%, respectively, p < 0.01). CONCLUSION Although spraying L-menthol did not improve the visibility of EGC under LCI observation, a significant increase in ΔEG was observed in LCI (jRCTs 021200027).

Abstract
Inflammatory bowel disease (IBD) are chronic relapsing diseases, affecting both children and adults with a life-long duration. An increased co-morbidity gives raise to fragility in the elderly. In this regard it should consider that several non-IBD colitides may mimic both ulcerative colitis and Crohn's disease. Moreover, chronic diseases represent a clinical challenge, mostly about treatment effectiveness. Finally, it is worth noting that patients with long-standing diseases - and elderly patients among them - have an increased malignancy risk when compared to general (non-IBD) population. Our paper aims to review the three main histological topics that play a role in the clinical management of IBD in the elderly, namely differential diagnosis, mucosal healing and IBD-associated dysplasia.

Abstract
Mucous membrane pemphigoid (MMP) is a rare, immune-mediated, vesiculobullous disease that predominantly affects the oral cavity and conjunctiva. In MMP, autoantibodies are directed against hemidesmosomal proteins in the basement membrane zone, most commonly BP180. Clinical signs and symptoms include gingival desquamation, erosions, and ulcerations. Differential diagnoses include other immune-mediated blistering diseases, such as bullous pemphigoid. Definitive diagnosis is reached through history taking, physical examination, tissue biopsy and/or serology testing. MMP, although not curable, is typically managed with topical or systemic corticosteroids, in addition to immunosuppressive therapies and biologic agents in recalcitrant cases. Untreated MMP can lead to life-threatening complications, such as blindness. As a condition that affects the oral cavity, it is important that dentists understand how to recognise, diagnose and manage the disease.

Abstract
Background/Aims Asymptomatic esophageal eosinophilia (aEE) is considered to be a potential precursor of eosinophilic esophagitis (EoE). However, there are few clinical parameters that can be used to evaluate the disease. Therefore, we aimed to clarify the factors involved in the symptoms of EoE by examining the clinicopathological differences between aEE and EoE. Methods We reviewed 41 patients with esophageal eosinophilia who underwent endoscopic ultrasonography and high-resolution manometry. They were divided into the aEE group (n=16) and the EoE group (n=25) using the Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease score. The patients' clinicopathological findings were collected and examined. Results The median Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease score was 3.0 in the aEE group and 10.0 in the EoE group. There was no significant difference in patient characteristics, endoscopic findings and pathological findings. The cutoff value for wall thickening was 3.13 mm for the total esophageal wall thickness and 2.30 mm for the thickness from the surface to the muscular layer (total esophageal wall thickness: 84.0% sensitivity, 75.0% specificity; thickness from the surface to the muscular layer: 84.0% sensitivity, 68.7% specificity). The high-resolution manometry study was abnormal in seven patients (43.8%) in the aEE group and in 12 (48.0%) in the EoE group. The contractile front velocity was slower in the EoE group (p=0.026). Conclusions The esophageal wall thickening in the lower portion of the esophagus is an important clinical factors related to the symptoms in patients with EoE.

Abstract
Esophageal intramural pseudodiverticulosis (EIPD) is a disease of unknown pathogenesis characterized by usually systemic, cystic dilatation of the excretory ducts of esophageal submucosal glands. In this article, I review the epidemiology, clinical manifestations, endoscopic findings, esophagographic findings, and histopathology of EIPD. I also discuss the etiology and possible pathogenesis of EIPD based on my experiences with this disease and a review of the literature. EIPD usually presents with dysphagia in middle-aged individuals. It is often complicated with secondary infections, most commonly candidiasis. On esophagography, EIPD is delineated as small, multiple, flask-shaped outward projections within the esophageal wall. In recent years, EIPD has been mainly diagnosed by endoscopic findings of multiple, localized, small mucosal depressions. The orifices of the "pseudodiverticula" periodically open and close, and excrete mucus onto the mucosal surface. On histopathological examination, the luminal surface of dilated ducts in EIPD is covered by multilayered, hyperplastic epithelial cells, but myoepithelial cells in the glandular acini are well preserved. Treatment of EIPD is usually symptomatic therapy, and prevention of the infectious complications is important. The etiology and pathogenesis of EIPD are largely unknown, but functional abnormalities of autonomic nerve fibers innervating the esophageal glands likely play an important role, since the structures of the glands are basically preserved in this disease.

Abstract
PURPOSE To evaluate preferred diagnostic tools and treatment decision-making factors in cases suspicious of mucous membrane pemphigoid (MMP) amongst ophthalmologists and cornea specialists. METHODS Web-based survey, consisting of 14 multiple choice questions, posted to the Cornea Society Listserv Keranet, the Canadian Ophthalmological Society Cornea Listserv, and the Bowman Club Listserv. RESULTS One hundred and thirty-eight ophthalmologists participated in the survey. Eighty-six percent (86%) of respondents were cornea trained and practiced in either North America or Europe (83%). Most respondents (72%) routinely perform conjunctival biopsies for all suspicious cases of MMP. For those who do not, fear that biopsy will exacerbate inflammation was the most common reason to defer investigation (47%). Seventy-one percent (71%) performed biopsies from perilesional sites. Ninety-seven percent (97%) ask for direct (DIF) studies and 60% for histopathology in formalin. Most do not recommend biopsy at other non-ocular sites (75%), nor do they perform indirect immunofluorescence for serum autoantibodies (68%). Immune-modulatory therapy is started following positive biopsy results for most (66%), albeit most (62%) would not let a negative DIF influence the choice of starting treatment should there be clinical suspicion of MMP. Differences in practice patterns as they relate to level of experience and geographical location are contrasted to the most up-to-date available guidelines. CONCLUSION Responses to the survey suggest that there is heterogeneity in certain practice patterns for MMP. Biopsy remains an area of controversy in dictating treatment plans. Identified areas of need should be targeted in future research.

Abstract
BACKGROUND The frequency of gallbladder carcinoma is high in pancreaticobiliary maljunction (PBM), and the mechanism of carcinogenesis is not well understood. METHODS The expression of γH2AX, the most sensitive marker for detecting DNA damage, was analyzed using immunohistochemistry in patients with PBM, in which the gallbladder and bile duct were simultaneously resected. Gallbladder and bile ducts were evaluated in non-neoplastic regions in 13 cases of PBM without cancer in the gallbladder and bile ducts. RESULTS The median frequencies of γH2AX expression in the bile duct and gallbladder within the same case were 5.9% (range 1.7-12.05%) and 9.9% (range 2.8-25%), respectively, and were significantly higher in the gallbladder mucosa (P < 0.0004). γH2AX expression strongly correlated in the bile duct and gallbladder (r = 0.9436, P < 0.0001). PBM caused marked mucosal damage to the gallbladder. CONCLUSIONS Mucosal damage may be involved in carcinogenesis, which may be useful for predicting malignant transformation.

Abstract
Endoscopic finding of invaginated appendiceal stump mimicking polyp is very rare. We present a case of patient with appendiceal stump mimicking cecal polyp covered with dysplastic mucosa which makes it even more rare. Polypoid lesions involving the appendiceal area represent a specific diagnostic-therapeutic dilemma. In these situations simple colonoscopic polypectomy poses increased risk for perforation. In our case biopsy of the polypoid cecal lesion revealed dysplastic mucosa. Due to the non-lifting sign and increased risk of perforation from simple polypectomy, polyp was removed by cecal wedge resection using combined endoscopic laparoscopic approach. Histopathology of the specimen confirmed medium dysplastic epithelium covering lymphoid follicles specific for appendix. In our case, decision on the need to remove the polyp, based on biopsy histology, was quite clear; however, the question is what should we have done if the biopsy finding was negative? In such a situation, conservative approach with endoscopic follow-up of the polyp and regular biopsy specimen analysis, or a more active approach of polyp removal should be considered. This issue can be discussed, however, we do believe that decision on approaching such patients should be made individually, based on the patient's age, comorbidities, general condition and operative risk.

Abstract
Pseudocarcinomatous hyperplasia of the tubal mucosa is a rare, reactive response to an underlying inflammatory or neoplastic process. We present a case of pseudocarcinomatous hyperplasia in a 26-year-old woman with clinical symptomatology of pelvic inflammatory disease, and a normal serum Ca 125-level (30 U/ml). The ultrasound finding showed presence of hydrosalpinx characterized with unilateral tubal enlargement in sausage-like shape that arose from the upper lateral margin of the uterus. The young age of the patient, presence of chronic inflammation, epithelial hyperplasia with unremarkable nuclear atypia and mitosis facilitated the right diagnosis. Pseudocarcinomatous hyperplasia can mimic neoplastic processes clinically and pathologically. Differential morphological and clinical features should be considered to ensure accurate diagnosis and proper management.

Abstract
DNA methylation is an epigenetic process altered in cancer and ageing. Age-related methylation drift can be used to estimate lifespan and can be influenced by extrinsic factors such as diet. Here, we report that non-pathogenic microbiota accelerate age-related methylation drift in the colon when compared with germ-free mice. DNA methylation analyses showed that microbiota and IL10KO were associated with changes in 5% and 4.1% of CpG sites, while mice with both factors had 18% alterations. Microbiota, IL10KO, and their combination altered 0.4%, 0.4%, and 4% of CpG island methylation, respectively. These are comparable to what is seen in colon cancer. Ageing changes were accelerated in the IL10KO mice with microbiota, and the affected genes were more likely to be altered in colon cancer. Thus, the microbiota affect DNA methylation of the colon in patterns reminiscent of what is observed in ageing and colorectal cancer.

Abstract
Purpose Ocular mucous membrane pemphigoid (OcMMP) is a rare eye disease characterized by relapsing-remitting or persisting long-lasting inflammatory events associated with progressive scarring. Despite long-term immunomodulating therapy, abnormal fibrosis keeps worsening in patients with OcMMP. This study investigates the fibrotic process in patients with OcMMP, as well as the critical role of the epithelium in modulating the local fibrosis. Methods In this prospective, observational pilot study, patients affected by long-lasting OcMMP were compared with age- and gender-matched healthy controls. Clinical grading was assessed, and conjunctival biopsy and impression cytology were performed. Conjunctival samples were used for quantifying the expression of transcripts regulating the inflammatory and fibrogenic processes. Results Ocular surface clinical and functional markers worsened in patients with OcMMP with fibrotic disease progression. In more advanced disease stages, both impression cytologies and conjunctival biopsies revealed increased tissue remodeling and profibrotic markers (α-SMA and TGF-β), and decreased levels of inflammatory markers (I-CAM1, IL-10, and IL-17). Increased epithelial expression of profibrotic markers and histological changes were detected. Conclusions Chronic OcMMP is characterized by a progressive, aberrant self-sustaining fibrotic process that worsens clinical signs and symptoms. Conjunctival epithelial cells may transdifferentiate into myofibroblast-like phenotypes when chronically exposed to high levels of inflammation, as in the case of OcMMP. Tissue remodeling markers in OcMMP could be used as early diagnostic, prognostic, and therapeutic biomarkers, harvested in a non-invasive and painless procedure such as impression cytologies.

Abstract
OBJECTIVES Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is historically associated with Helicobacter pylori (HP) infections in more than 80% of patients. However, the incidence of HP-negative MALT lymphoma has been increasing. The clinicopathologic features have not been well studied, and optimal management strategies remain unclear. METHODS The pathology database was searched for primary gastric MALT lymphomas diagnosed from 2000 to 2017. The clinical data and the slides were reviewed. The cases were divided for analysis into those with a background of chronic gastritis with HP, chronic gastritis without HP, and without either a background of chronic gastritis or HP. RESULTS Of 70 gastric MALT lymphoma cases identified, 26 (37% of total) had chronic gastritis and were positive for HP histologically (n = 23) or were HP positive by additional laboratory testing (n = 3). The remaining 44 (63% of total) cases were HP negative by histology. Within the HP-negative cases, 5 (11% of HP-negative cases) showed histologic gastritis while 39 (89% of HP-negative cases) did not have sufficient evidence of gastritis through review of slides (n = 18) or based on available pathology reports (n = 21). The HP-negative cases without gastritis had higher propensities to show a mass lesion on endoscopy compared with HP-positive cases (37.5% vs 11.1%, P = .02) at the initial diagnosis. The immunophenotype and rate of positive B-cell gene rearrangement were not significantly different between the 2 groups. While all HP-positive patients received antibiotics for HP eradication, treatment in the HP-negative group varied among antibiotics, radiation, rituximab, or chemotherapy. Among HP-negative patients with available follow-up, 13 (39%) showed disease recurrence, similar to the recurrence rate in HP-positive patients; however, no individual from either group has died of the disease thus far. CONCLUSIONS The incidence of HP-negative MALT lymphoma is increasing, and in our practice, it is currently more common than HP-associated MALT lymphomas. The pathophysiology of HP-negative MALT lymphoma without chronic gastritis remains unclear. Follow-up data in our study suggest that the prognosis of these cases is excellent despite varied management modalities.

Abstract
Introduction Heartburn pathogenesis in GERD remains incompletely understood. We aimed to identify differences in the immune cell signature and sensory mucosal markers between reflux phenotypes and healthy asymptomatic subjects. Methods Thirty-seven patients with heartburn symptoms were phenotyped endoscopically and with objective reflux studies into erosive reflux disease (ERD) (N=10), nonerosive reflux disease (NERD) (N=9), functional heartburn (FH) (N=9), and Barrett's esophagus (BO) (N=9). Bulk mRNA-sequencing(RNA-seq) was conducted on RNA extracted from endoscopic biopsies, and immune cell deconvolution analysis was performed using CIBERSORT. RNA-seq findings were validated by immunofluorescent staining for CD1a, nerve growth factor (NGF), and mast cell tryptase in corresponding patient biopsies. Results Transcriptomic analysis detected higher mast cell abundance in BO, ERD, and NERD compared to healthy controls (p<0.05), with decreased dendritic cell infiltration in BO, ERD, and NERD patients compared to healthy controls and FH patients. CD1a-positive dendritic cell infiltration was significantly higher in the healthy esophageal mucosa at protein level compared to BO (p=0.0005), ERD (p=0.0004), and FH patients (p=0.0096). Moreover, NGF co-expression on mast cells in GERD patients was significantly higher than in healthy controls (p=0.0094). Discussion The mucosa in patients with GERD had a significant increase in NGF expression on mast cells, suggesting an upregulation of signalling for neuronal sprouting in GERD. Moreover, decreased dendritic cell abundance in GERD esophageal mucosa may play a role in reduced oral tolerance and development of subsequent immune responses which may participate in esophageal sensitivity.

Abstract
BACKGROUND Esophageal carcinoma is a highly aggressive digestive cancer responsible for a notable proportion of cancer-related deaths worldwide. Its elevated metastatic rate contributes to a poor prognosis in affected patients. In this case review, we aim to summarize the metastatic characteristics of intramural gastric metastasis (IGM) in mucosal esophageal squamous carcinoma. CASE SUMMARY A 56-year-old man was admitted to our hospital because of a dry cough with an esophageal sensation for one year. Endoscopic examination revealed a 2.0 cm 1.0 cm, superficial esophageal squamous cell carcinoma, and the patient underwent endoscopic submucosal dissection (ESD). Fifteen months after ESD, positron emission tomography/computed tomography revealed that the metabolism of the stomach cardia wall had increased slightly. However, the mucosa of the gastric cardia was smooth under gastroendoscopy. Two years after ESD, endoscopic examination revealed a giant gastric cardia carcinoma, while the esophageal mucosa was smooth, and no advanced cancer was found. A biopsy of the gastric cardia indicated squamous-cell carcinoma. The patient received immunochemotherapy and radiotherapy for esophageal cancer for 8 mo and is currently under follow-up. CONCLUSION Early-stage esophageal carcinoma with IGM is rare. Despite the ESD of the primary lesion, IGM may still occur and should be closely monitored after ESD.

Abstract
Pemphigus is an autoimmune blistering disease with two major subtypes, pemphigus vulgaris (PV) and pemphigus foliaceus (PF). Although most patients with PV show oral lesions, cutaneous type PV (C-PV) is a rare subtype clinically characterized by predominant cutaneous involvement with no or subtle mucosal lesions. Patients with PF present with only skin involvement; they do not have mucosal lesions. Serologically, autoantibodies against desmoglein (Dsg) 3 and Dsg1 are observed in C-PV whereas PF is associated with anti-Dsg1 antibodies only. Herein, we describe three cases of pemphigus presenting with predominant skin lesions and no mucosal involvement despite high anti-Dsg 3 autoantibody levels in chemiluminescent enzyme immune assays (CLEIAs). In addition, anti-Dsg 1 autoantibodies were positive in patients 2 and 3, but negative in patient 1 based on CLEIAs. Histological examination of the skin showed suprabasal acantholysis in patients 1 and 2, and blister formation in the upper epidermis in patient 3. Histopathology of the oral membrane in patients 1 and 2 showed subtle acantholysis in the suprabasal layer. Thus, we diagnosed patients 1 and 2 as having cutaneous type PV and patient 3 as having PF. Ethylenediaminetetraacetic acid-treated enzyme-linked immunosorbent assay demonstrated a low proportion of anti-Dsg3 autoantibodies recognizing Ca2+ -dependent epitopes, antibodies against which are thought to be the main contributor to acantholysis. Thus, along with Dsg1 antibodies, weak anti-Dsg3 antibodies could induce acantholysis in the skin, but they are insufficient to induce mucosal lesions.

Abstract
Mucosal melanoma remains a rare cancer with high mortality and a paucity of therapeutic options. This is due in significant part to its low incidence leading to limited patient access to expert care and downstream clinical/basic science data for research interrogation. Clinical challenges such as delayed and at times inaccurate diagnoses, and lack of consensus tumor staging have added to the suboptimal outcomes for these patients. Clinical trials, while promising, have been difficult to activate and accrue. While individual institutions and investigators have attempted to seek solutions to such problems, international, national, and local partnership may provide the keys to more efficient and innovative paths forward. Furthermore, a mucosal melanoma coalition would provide a potential network for patients and caregivers to seek expert opinion and advice. The Melanoma Research Foundation Mucosal Melanoma Meeting (December 16, 2022, New York, USA) highlighted the current clinical challenges faced by patients, providers, and scientists, identified current and future clinical trial investigations in this rare disease space, and aimed to increase national and international collaboration among the mucosal melanoma community in an effort to improve patient outcomes. The included proceedings highlight the clinical challenges of mucosal melanoma, global clinical trial experience, basic science advances in mucosal melanoma, and future directions, including the creation of shared rare tumor registries and enhanced collaborations.

Abstract
OBJECTIVE We aimed to characterize the histology and the clinicodemographic features of mucoepidermoid carcinoma (MEC), showing continuity with the oral surface mucosa. STUDY DESIGN We reviewed 138 cases of intraoral MEC to identify cases that showed continuity with the surface mucosa and compared their clinicodemographic findings with those of MECs not showing continuity. We compared the sex ratio using the 2-sample Z-test and compared the age distribution using the 2-sample Kolmogorov-Smirnov test. RESULTS Of the 138 cases examined, 14 showed continuity with the surface mucosa. Their histology showed surface mucosa with an apparent transition to an infiltrating tumor with mucous, intermediate, and epidermoid tumor cells growing in solid and cystic patterns. Their clinical appearance ranged from firm submucosal nodules to erythematous to ulcerated lesions. They showed a strong female predilection (6:1) and sharply bimodal age distribution, with sharp peaks in the fourth and seventh decades. CONCLUSIONS Mucoepidermoid carcinomas that show continuity have a demographic pattern distinct from that of conventional MECs, showing a striking female predilection and bimodal age distribution and suggesting a difference in etiology. Pathologists should remain aware that MEC in the oral cavity can have a histologic appearance of surface origin to reach the correct diagnosis.

Abstract
Esophageal stricture caused by complete circumferential endoscopic submucosal dissection (ESD) of extensive esophageal squamous cell carcinoma (ESCC) is a major concern and can result in a low quality of life. Normal mucosa may remain within a complete circumferential lesion of ESCC in some cases. We herein report a case of ESCC in which a complete circumferential lesion was treated with ESD while leaving an island of normal mucosa within it. This case demonstrates that preserving areas of normal mucosa within lesions during complete circumferential ESD is not technically difficult and may be an effective measure for preventing esophageal stricture.

Abstract
OBJECTIVES Lobular capillary hemangioma (LCH) rarely involves the gastrointestinal (GI) tract. This study describes clinicopathologic features of LCH in a cohort of GI cases. METHODS We defined lobular capillary hemangioma as "a proliferation of capillary-sized blood vessels arranged at least focally in a lobular configuration," searched departmental archives for cases, and recorded clinicopathologic findings. RESULTS We identified 34 GI tract LCHs from 16 men and 10 women; 4 patients had multiple lesions. Mean age was 64 years. Cases arose in the esophagus (n = 7), stomach (n = 3), small bowel (n = 7), and colorectum (n = 17). Twelve patients had anemia or rectal bleeding. No patients had a known genetic syndrome. The lesions manifested as mucosal polyps, with median size of 1.3 cm. Microscopically, 20 lesions were ulcerated, and most involved the mucosa, with 9 extending into the submucosa. Vessel dilation was present in 27 patients, endothelial hobnailing in 13, hemorrhage in 13, and focal reactive stromal atypia in 2. Follow-up information was available for 10 patients, none of whom developed same-site recurrence. Six of the 26 cases (23%) were extradepartmental consultations, including 2 of the multifocal cases. CONCLUSIONS Gastrointestinal tract LCHs often arise as colorectal polyps. They are typically small but can reach a few centimeters in size and can be multifocal.

Abstract
Esophageal tuberculosis (ET) is an extremely rare disease and herein, we present an ET case. Endoscopic findings of ET are variable and diverse and can be easily mistaken for malignancy. A definitive diagnosis of ET is difficult to make with white light endoscopy alone, and the diagnostic yield of a biopsy is low in secondary ET cases with normal overlying mucosa. Although the findings of conventional endoscopy and endoscopic ultrasonography in ET have been reported so far, few reports have described the findings of magnifying endoscopy with narrow-band imaging (ME-NBI). Dilated microvessels without irregularities on ME-NBI may be useful to differentiate secondary ET from esophageal carcinoma, since the findings suggest compression from the depth. Although rare, ET has to be considered in the differential diagnosis for any unexplained esophageal lesions.

Abstract
BACKGROUND & AIMS The nature of the involvement of esophageal tissue in eosinophilic esophagitis (EoE) is unclear. We estimated the intrabiopsy site agreements of the EoE Histologic Scoring System (EoEHSS) scores for the grade (degree) and stage (extent) of involvement of the esophageal epithelial and lamina propria and examined if the EoE activity status influenced the intrabiopsy site agreement. METHODS Demographic, clinical, and EoEHSS scores collected as part of the prospective Outcome Measures for Eosinophilic Gastrointestinal Diseases Across Ages study were analyzed. A weighted Cohen's kappa agreement coefficient (k) was used to calculate the pairwise agreements for proximal:distal, proximal:middle, and middle:distal esophageal biopsy sites, separately for grade and stage scores, for each of the 8 components of EoEHSS. A k > 0.75 was considered uniform involvement. Inactive EoE was defined as fewer than 15 eosinophils per high-powered field. RESULTS EoEHSS scores from 1263 esophageal biopsy specimens were analyzed. The k for the stage of involvement of the dilated intercellular spaces across all 3 sites in inactive EoE was consistently greater than 0.75 (range, 0.87-0.99). The k for lamina propria fibrosis was greater than 0.75 across some of the biopsy sites but not across all 3. Otherwise, the k for all other features, for both grade and stage, irrespective of the disease activity status, was 0.75 or less (range, 0.00-0.74). CONCLUSIONS Except for the extent of involvement of dilated intercellular spaces in inactive EoE, the remaining epithelial features and lamina propria are involved unevenly across biopsy sites in EoE, irrespective of the disease activity status. This study enhances our understanding of the effects of EoE on esophageal tissue pathology.

Abstract
IMPORTANCE Laminin-332 is an important component of the basement membrane. Recently, autoantibodies to Laminin-332 have been described in several autoimmune diseases. Many of these autoimmune diseases have a high incidence of malignancy. The importance of Laminin-332 autoantibodies and its relationship to malignancy is highlighted by using Laminin-332 Pemphigoid (LM-332Pg) as a prototype. OBJECTIVE To identify several autoimmune diseases that have autoantibodies to Laminin-332 present, and to determine the prevalence of malignancy in them. Using Laminin-332 Pemphigoid (LM-332Pg) as a prototype, to compare clinical profiles of LM-332Pg patients with and without cancer. By identifying the temporal detection of cancer, can the influence of autoantibodies to Laminin-332 on prognosis be determined. EVIDENCE REVIEW A literature search was conducted to identify autoimmune and inflammatory diseases in which autoantibodies to Laminin-332 were present. Subsequently, the rate of malignancy in these autoimmune diseases was determined. A search for publications on LM-332Pg patients to determine cancer rates and clinical outcomes to examine if a relationship can be proposed, was performed. FINDINGS Autoantibodies to Laminin-332 were detected in recent studies of systemic lupus erythematosus (SLE), psoriasis, bronchiolitis obliterans (BO), graft-vs-host disease (GVH), bullous pemphigoid (BP), lichen planus (LP), epidermolysis bullosa acquisita (EBA), and membranous glomerulonephropathy (MGN). A high incidence of cancer rate was reported in these autoimmune diseases including primary Sjögren's syndrome (pSS), systemic sclerosis (SS), dermatomyositis (DM), multiple sclerosis (MS), immune thrombocytopenia purpura (ITP), and rheumatoid arthritis (RA). Data analysis demonstrated that LM-332Pg patients had a higher risk of developing ovarian, uterine, lung, gastric cancers and leukemia. The incidence for breast cancer was lower, when compared with global cancer rates. Patients diagnosed with cancer after the presence of LM-332Pg had higher rates of mortality and lower rates of remission, compared to those diagnosed with cancer prior to the discovery/diagnosis of LM-332Pg. When studied, levels of Laminin-332 autoantibodies correlated with the presence or absence of malignancy. CONCLUSIONS AND RELEVANCE Preliminary analysis suggests that autoantibodies to Laminin-332 are present in multiple autoimmune diseases, which also have a high incidence of malignancy. Detailed analysis of available data highlights that patients who developed LM-332Pg after cancer was diagnosed, had a more favorable prognosis, compared to patients who developed cancer when LM-332Pg was previously present. Preliminary data would suggest that autoantibodies to Laminin-332 could serve as an important biomarker in certain patients, for correlation with possible incidence of malignancy.

Abstract
BACKGROUND Tumor growth pattern correlates with outcomes in patients with esophageal squamous cell carcinoma (ESCC), however, the clinical significance of the tumor growth pattern in pT1a-lamina propria mucosa (LPM) type of ESCC was unclear. This study was conducted to clarify clinicopathological features of tumor growth patterns in pT1a-LPM type ESCC and the relationship between tumor growth patterns and magnifying endoscopic findings. METHODS Eighty-seven lesions diagnosed as pT1a-LPM ESCC were included. Clinicopathological findings including tumor growth pattern and narrow band imaging with magnifying endoscopy (NBI-ME) in the LPM area were investigated. RESULTS Eighty-seven lesions were classified as infiltrative growth pattern-a (INF-a): expansive growth (n = 81), INF-b: intermediate growth (n = 4) and INF-c: infiltrative growth pattern (n = 2). Lymphatic invasion was shown in one INF-b and one INF-c lesion. NBI-ME and histopathological images were matched for 30 lesions. The microvascular pattern was classified into types B1 (n = 23) and B2 (n = 7) using the JES classification. All 23 type B1 lesions were classified as INF-a without lymphatic invasion. Type B2 lesions were classified as INF-a (n = 2), INF-b (n = 4) and INF-c (n = 1), and lymphatic invasion was present in two lesions (INF-b and INF-c). The rate of lymphatic invasion was significantly higher in type B2 than type B1 (p = 0.048). CONCLUSIONS The tumor growth pattern of pT1a-LPM ESCC was mostly INF-a in type B1 patterns. Type B2 patterns are rarely present in pT1a-LPM ESCC, however lymphatic invasion with INF-b or INF-c was frequently observed. Careful observation before endoscopic resection with NBI-ME is important to identify B2 patterns to predict histopathology.

Abstract
Combined autofluorescence (AF) and diffuse reflectance (DR) spectroscopies have been expected to offer enhanced diagnostic accuracies for noninvasive early detection of mucosa lesions, that is, oral cavity carcinoma and cervical carcinoma. This work reports on a hybrid AF and DR spectroscopic system that is developed for quantification and diagnosis of mucosa abnormalities. The system stability and reliability are firstly assessed by phantom experiments, showing a measurement variation lower than 1% within 20 min. In vitro and in vivo validations are then conducted for tissue identification and lesion differentiation. For enhanced decision, a data-driven diagnosis algorithm is explored in pilot under different experimental configurations. The results conclude a promising accuracy of >96% for the in vivo classification as well as an excellent sensitivity of >88% for the in vitro mucosa lesions detection, and demonstrate sound potential of the system in early detection of mucosa lesions.

Abstract
OBJECTIVES Bullous pemphigoid has previously been linked to radiotherapy, but here we report the first case of MMP suspected to be a consequence of RT. METHODS The patient described is an 85-year-old male who underwent RT to treat squamous cell carcinoma of the palatine tonsil. Shortly after therapy, the patient developed blisters with worsening dyspnea and dysphonia. RESULTS This patient was successfully treated with a combination of oral immunosuppressants and surgical intervention. CONCLUSION This incident underscores that not all episodes of mucosal ulceration following radiation are a result of mucositis and MMP should be considered in the differential.

Abstract
BACKGROUND The therapeutic approach after endoscopic submucosal dissection (ESD) for esophageal squamous cell carcinoma (ESCC) diagnosed as pathological T1a-muscularis mucosa (pT1a-MM) without lymphovascular involvement (LVI) remains uncertain. We aimed to determine whether observation after ESD is acceptable for patients without LVI showing pT1a-MM cancer. METHODS We retrospectively registered 566 ESCC patients who were treated with ESD at ten institutions between January 2007 and December 2015. Of those, 447 cases showing pT1a-epithelium/lamina propria mucosa (EP/LPM) without LVI and vertical margin (VM) (EP/LPM group), and 41 cases showing pT1a-MM without LVI and VM (MM group) were analyzed in this investigation. The clinical outcomes were assessed between the groups. RESULTS The 5 year cumulative incidence of metastatic recurrence was 0.5% and 3.3% in the EP/LPM and MM groups, respectively (P = 0.121). Two cases showing pT1a-EP/LPM and one showing pT1a-MM experienced lymph node recurrence. The 5 year cumulative incidence of local recurrence was 1.5% and 3.8% in the EP/LPM and MM groups, respectively (P = 0.455). The 5 year disease-specific survival (DSS) rate was 99.3% and 96.6% in the EP/LPM and MM groups, respectively (P = 0.118), whereas the 5 year overall survival rate was significantly higher in the EP/LPM group than in the MM group (92.6% versus 81.1%, respectively; P = 0.021). CONCLUSIONS As regards metastatic recurrence and DSS, ESCC patients with pT1a-MM without LVI showed favorable outcomes that were equivalent to those with pT1a-EP/LPM, even when they were not treated with additional therapy after ESD.

Abstract
BACKGROUND Melanoma is a predominantly cutaneous malignancy associated with sun exposure. Mucosal melanoma is rare and carries a distinct pathogenesis from cutaneous tumors. The vermillion of the lip is a unique site that divides cutaneous from mucosal tissues. Tumors arising on the dry aspect are classified as cutaneous and those of the wet aspect are mucosal. The distinction is importation in tumor staging as all mucosal melanomas are classified as T3-T4b under the current 8th edition American Joint Committee of Cancer (AJCC) guidelines. METHODS We describe a case of early stage melanoma of the vermillion with associated mucosal melanoma in situ. We discuss nuances of management at this site and the distinctions between cutaneous versus mucosal melanomas with a review of the literature. RESULTS Our patient was treated surgically with 2-3 cm margins. Residual melanoma in situ was present at the mucosal margin on final pathology which required a second surgery for margin revision. The case was discussed at tumor board with recommendation for no further treatment. CONCLUSIONS The nuances between the vermillion and mucosal lip must be understood for appropriate staging and treatment of melanomas. The paucity of literature on melanomas affecting this site render management decisions challenging. Multidisciplinary discussion is essential for guiding care.

Abstract
INTRODUCTION Discordance between gastrointestinal (GI) symptoms and endoscopic inflammation in patients with ulcerative colitis (UC) is known. However, the correlations between symptoms and endoscopic and histologic (endo-histologic) mucosal healing and remains unknown. METHODS We performed a secondary analysis of prospectively collected clinical, endoscopic, and histologic data on 254 colonoscopies from 179 unique adults at a tertiary referral center from 2014 to 2021. Spearman's rank was used to assess the correlation between patient reported outcomes and objective assessments of disease activity, as measured by validated instruments: Two-item patient-reported outcome measure (PRO-2) for stool frequency and rectal bleeding, the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) for endoscopic inflammation, and the Geboes score for histologic inflammation. The predictive value of objective assessments of inflammation and clinical symptoms was described using sensitivity, specificity, and positive/negative predictive value. RESULTS One-quarter (28%, 72/254) of cases were in endo-histologic remission; of these, 25% (18/72) report GI symptoms (22% diarrhea; 6% rectal bleeding). Endo-histologically active disease had higher sensitivity (95% rectal bleeding; 87% diarrhea) and negative predictive value (94% rectal bleeding, 78% diarrhea) for clinically active disease compared to active disease on endoscopic (77%) or histologic assessment only (80%). The specificity of endo/histologic inflammation for GI symptoms was < 65%. PRO-2 was positively correlated with endoscopic disease activity (Spearman's rank 0.57, 95% CI 0.54-0.60, p < 0.0001) and histologic disease activity (Spearman's rank 0.49, 0.45-0.53, p < 0.0001). CONCLUSION One-quarter of patients with ulcerative colitis in endo-histologic (deep) remission have gastrointestinal symptoms, more commonly with diarrhea than rectal bleeding. Endo-histologic inflammation has high sensitivity (≥ 87%) for diarrhea/rectal bleeding.

Abstract
Esophageal stricture is a debilitating condition that negatively impacts patients' quality of life after undergoing endoscopic mucosal resection (EMR). Despite its significance, this disease remains underexplored due to the lack of a stable animal model. Under direct visualization with choledochoscopy, we retrogradely damaged the esophageal mucosal layer through the gastrostomy to create a rat model of esophageal stricture. The development of histological defects in the mucosal layer was assessed over a 2-week period after model induction. Then the models were evaluated using X-ray barium radiography, Hematoxylin-Eosin, Masson's trichrome, Sirius red, and Victoria blue staining, multiphoton microscopic imaging. Additionally, the molecular mechanisms of esophageal stricture were explored by conducting RNA transcriptome sequencing, PCR, immunohistochemistry, and immunofluorescence staining. We successfully established fifteen rat models of esophageal stricture by injuring the mucosal layer. In the model group, the mucosal defect initially occurs and subsequently repaired. The epithelium was absent and was plastically remodeled by collagen during the acute inflammatory phase (Day 1), proliferation phase (Day 7), anaphase of proliferation (Day 10), and plastic remodeling phase (Day 14). We observed increased expression of COL1A1, acta2, FGF, IL-1, and TGF-β1 pathway in the model group. We established a highly repeatable rat model of esophageal stricture, and our results suggest that the mucosal defect of the esophagus is a critical factor in esophageal stricture development, rather than damage to the muscularis layer. We identified Atp4b, cyp1a2, and gstk1 as potential targets for treating esophageal stricture, while the TGF-β pathway was found to play an important role in its development.

Abstract
INTRODUCTION Curative management after endoscopic resection (ER) for esophageal squamous cell carcinoma (ESCC), which invades the muscularis mucosa (pMM-ESCC) or shallow submucosal layer (pSM1-ESCC), has been controversial. METHODS We identified patients with pMM-ESCC and pSM1-ESCC treated by ER. Outcomes were the predictive factors for regional lymph node and distant recurrence, and survival data were based on the depth of invasion, lymphovascular invasion (LVI), and additional treatment immediately after ER. RESULTS A total of 992 patients with pMM-ESCC (n = 749) and pSM1-ESCC (n = 243) were registered. According to the multivariate Cox proportional hazards analysis, pSM1-ESCC (hazard ratio = 1.88, 95% confidence interval 1.15-3.07, P = 0.012) and LVI (hazard ratio = 6.92, 95% confidence interval 4.09-11.7, P < 0.0001) were associated with a risk of regional lymph node and distant recurrence. In the median follow-up period of 58.6 months (range 1-233), among patients with risk factors (pMM-ESCC with LVI or pSM1-ESCC), the 5-year overall survival rates, relapse-free survival rates, and cause-specific survival rates of patients with additional treatment were significantly better than those of patients without additional treatment; 85.4% vs 61.5% ( P < 0.0001), 80.5% vs 53.3% ( P < 0.0001), and 98.5% vs 93.1% ( P = 0.004), respectively. There was no difference in survival rate between the chemoradiotherapy and surgery groups. DISCUSSION pSM1 and LVI were risk factors for metastasis after ER for ESCC. To improve the survival, additional treatment immediately after ER, such as chemoradiotherapy or surgery, is effective in patients with these risk factors.

Abstract
We have developed a cell-based outer vocal fold replacement (COVR) as a potential therapy to improve voice quality after vocal fold (VF) injury, radiation, or tumor resection. The COVR consists of multipotent human adipose-derived stem cells (hASC) embedded within a three-dimensional fibrin scaffold that resembles vocal fold epithelium and lamina propria layers. Previous work has shown improved wound healing in rabbit studies. In this pilot study in pigs, we sought to develop methods for large animal implantation and phonatory assessment. Feasibility, safety, and structural and functional outcomes of the COVR implant are described. Of eight pigs studied, six animals underwent COVR implantation with harvest between 2 weeks and 6 months. Recovery of laryngeal tissue structure was assessed by vibratory and histologic analyses. Recovery of voice function was assessed by investigating acoustic parameters that were derived specifically for pigs. Results showed improved lamina propria qualities relative to an injured control animal at 6 months. Acoustic parameters reflected voice worsening immediately after surgery as expected; acoustics displayed clear voice recovery in the animal followed for 6 months after COVR. These methods form the basis for a larger-scale long-term pre-clinical safety and efficacy study.

Abstract
AIMS A subset of patients with urothelial carcinoma (UCa) and lamina propria (LP) invasion in bladder biopsies/transurethral resections (TURs) are at significant risk for recurrence and have increased rates of progression to UCa with muscularis propria (MP) invasion. The clinicopathologic features of this patient population has not been well characterised in the Pathology literature. METHODS We performed a search through our urologic pathology files and expert consult cases of the senior author for bladder biopsies/TURs of UCa with LP invasion and variant/divergent histology from 2014 to 2020. Patients with a prior diagnosis of UCa with MP invasion or upper tract UCa were excluded. Clinicopathologic data were obtained. RESULTS Ninety-five patients with at least one biopsy/TUR of UCa with LP invasion and variant/divergent histology were identified. Mean patient age was 72 years (range: 46-92 years) with a male predominance 2.3:1. Initial variant/divergent histologies identified were: glandular (35.8%), squamous (23.2%), micropapillary (20%), clear cell/lipid rich (12.6%), diffuse/signet ring/plasmacytoid (10.5%), nested (9.5%), sarcomatoid (6.3%), poorly differentiated/anaplastic (4.2%), small cell (2.1%), lymphoepithelioma-like (2.1%), osteoclast-like giant cells (1.1%) and tumour giant cells (1.1%). Two or more variant histologies were identified in 18.9% of these cases. The rate of micropapillary UCa was significantly higher in multifocal tumours compared with unifocal tumours (37% vs 7.1%). CONCLUSIONS In our cohort of patients undergoing early repeat biopsy/TUR, 75% of patients had persistent UCa. Additionally, almost 25% of patients had a prior diagnosis of UCa without a variant/divergent histology identified. Our findings highlight the critical role of repeat biopsy/TUR especially in a subset of patients who have variant/divergent histology, even in the absence of MP invasion.

Abstract
ABSTRACT Prostate cancer metastasis to the rectal mucosa, a relatively rare metastatic site, leads to a higher clinical stage and poorer prognosis. A 65-year-old man with prostate cancer underwent 18 F-prostate-specific membrane antigen (PSMA) PET/CT for staging. Intense 18 F-PSMA uptake occurred at the primary lesion, bladder, adjacent seminal vesicle, and rectum. PET/CT imaging revealed increased homogeneous round activity of the rectal wall. The final diagnosis was prostate cancer metastasis to the rectal mucosa. This case suggested that 18 F-PSMA PET/CT may assist in locating rare metastases of prostate cancer, with potential value for early staging.
