A 70's male was admitted to our hospital with complaints of anorexia and abdominal pain. CT showed thickening of the ascending colon. Colonoscopy revealed multiple diverticula of the ascending colon, but no tumor on the mucosa. The patient was diagnosed as a case of diverticulitis of the ascending colon and was advised laparoscopic ileocecal resection. The resected specimen showed wall thickening; however, no remarkable findings were observed, with the exception of multiple diverticula on the mucosal surface. Histological examination showed well-differentiated tubular adenocarcinoma extending into the serosa probably arising from the diverticulum. Chemotherapy was performed after surgery. The patient died due to peritoneal dissemination from the ascending colon cancer 14 months after surgery.

Colonic neuroendocrine tumors (NETs), excluding rectal NETs, are often described as relatively common and aggressive, with inferior median survival compared with other gastrointestinal (GI) primary sites. However, epidemiological databases may conflate well-differentiated NETs with poorly differentiated neuroendocrine carcinomas (NECs), leading to a lack of precise data on the prevalence, clinical behavior, and prognosis of well-differentiated colonic NETs. We analyzed a large institutional database to identify patients with well-differentiated NETs originating in the colon, excluding rectal NETs.

Total proctocolectomy with ileal pouch anal anastomosis is the standard of care for patients with severe ulcerative colitis. We generated a cell-type-resolved transcriptional and epigenetic atlas of ileal pouches using scRNA-seq and scATAC-seq data from paired biopsy samples of the ileal pouch and the ileal segment above the pouch (pre-pouch) from patients (male=4, female=2), and paired biopsies of the terminal ileum and ascending colon from healthy individuals (male=3, female=3) serving as reference. Our study finds an additional population of absorptive and secretory epithelial cells within the pouch but not the pre-pouch.

Background: Neutropenic enterocolitis is a serious gastrointestinal complication that can develop in patients undergoing chemotherapy or other immunosuppressive treatments. It is characterized by inflammation and necrosis of the bowel, and most commonly affects the cecum and ascending colon. Although individual case reports have described the features of NE, a comprehensive synthesis of all the published cases is required.

Background: Colorectal cancer (CRC) causes substantial morbidity and mortality internationally. In Hungary, the incidence and mortality of CRC are among the world's highest. Fortunately, CRC is a highly preventable disease, since there is a long asymptomatic phase before neoplastic transformation.
