Villous adenomas of the urinary tract are rare as compared to urothelial carcinoma. We report a case of urinary bladder villous adenoma in a 90-year-old woman. Cystoscopic examination revealed a papillary tumour in the diverticulum at the posterior wall of the urinary bladder. Transurethral resection was performed and histopathological examination revealed predominantly tubulovillous architecture, and showed an identical immunohistochemical profile to villous adenoma associated with cystitis glandularis.

Background: Despite reports indicating that polyps proximal to the splenic flexure have higher rates of metachronous colorectal adenocarcinoma (CRC), the role of adenoma location on surveillance recommendations remains unclear. This study aimed to analyze the association between index polyp location and post-colonoscopy CRC among participants of the Minnesota Colon Cancer Control Study (MCCCS).
Methods: The MCCCS randomized 46,551 patients 50-80 years to usual care, annual, or biennial screening with fecal occult-blood testing (FOBT).

Traditional serrated adenomas (TSAs) of the duodenum are rare lesions with potential for malignant transformation. We present the case of a 44-year-old female with a history of bariatric surgery who presented with worsening abdominal pain, nausea, and significant weight loss. Imaging studies, including MRI, revealed a 3.

Background Colorectal cancer (CRC) remains a significant public health challenge. Patients having abnormal faecal immunochemical test (FIT) results are offered a colonoscopy. The effectiveness of colonoscopies can, however, often be challenged by the occurrence of missed polyps.

PGA has been increasingly recognized as a histologically and molecularly distinct entity; however, its endoscopic features have not been precisely described. This study aims to investigate the endoscopic characteristics of duodenal PGA, including the association of their putative precursors, Brunner's gland hyperplasia (BGH), and gastric epithelial heterotopia/metaplasia (GEM/H).
