- Sessile serrated adenomas/polyps (SSA/Ps), recently called sessile serrated lesions, have a neoplastic pathway in the large intestine and are treated as lesions with malignant potential. There are a few reports of traditional serrated adenomas in the duodenum but no reports of duodenal SSA/Ps. A 66-year-old man underwent screening upper gastrointestinal endoscopy and was found to have a white ele…

Excision of the lesion displayed a benign sebaceous neoplasm taking origin from the surface squamous epithelium which invaginated into the stroma to create crypts resembling the conjunctival pseudoglands of Henle or the glands of Lieberkuhn of the small intestine. Scattered sebaceous cells were also d…

- Risk of Small Bowel Adenocarcinoma, Adenomas, and Carcinoids in a Nationwide Cohort of Individuals With Celiac Disease. [Journal Article]
- CONCLUSIONS: In an analysis of a nationwide pathology database in Sweden, we found the absolute risk of small bowel adenocarcinoma is low in individuals with CD. However, risks of small bowel adenocarcinoma and adenomas (but not carcinoids) are significantly increased in people with CD compared to people without this disease.

- Villous Morphology in Urinary Bladder Biopsy: An Approach to Diagnosis. [Review]
- Villous morphology in urinary bladder biopsy is a relatively uncommon finding. Villi are slender, finger-like structures that are commonly seen in the small intestine or in neoplastic lesions of gastrointestinal lineage/differentiation. Importantly, placenta also exhibits villi that are morphologically and functionally different from the intestinal one. Majority of the neoplastic lesions of urina…

- The tumorigenesis of non-ampullary duodenal epithelial tumors (NADETs) might be different between the oral and anal sides of Vater's papilla. We conducted an immunohistological review to elucidate the clinicopathological features according to the tumor location and phenotypic classification. A review of an institutional database identified 121 patients with 125 superficial NADETs. NADETs were his…

- Small Intestinal Tumors: A Rare Case of Tubulovillous Adenoma in Duodenum. [Retracted Publication]
- The small intestine is a relatively privileged organ; primary tumors are uncommon among malignancies of the gastrointestinal tract, with an average annual incidence rate of 9.9 per million people. Among these uncommon tumors, duodenal tumors are even rarer with an average incidence rate of 0.4% only. Histopathological examination mostly shows villous type. Tubulovillous histology is extremely rar…

- Villous Adenoma Arising in the Native Bladder Mucosa and the Upper Urinary Tract With Coexisting Neuroendocrine Carcinoma Following Augmentation Cystoplasty. [Case Reports]
- Villous adenomas arising in the bladder following augmentation cystoplasty procedures are exceedingly rare. Even rarer is their occurrence in the native bladder mucosa and the upper urinary tract. In this article, we present a unique case of multifocal recurrent villous adenoma involving native bladder mucosa of an augmented bladder, bilateral ureters, and renal pelvis, with coexistent foci of ad…

- Frequency indices of tubulovillous adenoma are higher than the ones of colorectal cancer, and probably, the majority of adenomas are prone to malignancy. It is often impossible to determine which adenoma tends to tumorous neoplasia. However, increase in the adenomas and expressed dysplasia contribute to adenomas malignant transformation. In this regard, the purpose of the study is to evaluate cel…

The patient was a 72-year-old man who was referred to our hospital with a positive fecal blood test. Colonoscopy revealed advanced cancer in the descending colon. As part of the preoperative examination, for the colonic cancer, upper gastrointestinal endoscopy was performed. En…

Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound are used in adults to assess and treat these lesions, although there are no instruments designed specifically for use in young children. A six-year-old girl was admit…

- CONCLUSIONS: There is no significant difference between endoscopic and local operative resections of benign adenomas of ampulla of Vater; recurrences are more common when two or more endoscopic resections are required for complete tumor removal. Appropriate adenomas for endoscopic resection included tumors <3.6 cm that do not extend far enough intraductally (on EUS) to preclude an endoscopic snare ampullectomy.
