Abstract

A 77-year-old female admitted to our hospital after a positive test for fecal occult blood. The colonoscopy showed a reddish granular mucosa area in the cecum, and the biopsy revealed the possibility of lymphoma. Colonoscopy was re-examined, and magnifying endoscopy with NBI showed a type I pit pattern with capillary vessels that were partially expanded. Since we needed a specimen without crushig, CSP was performed for a wide range sampling. Pathological examination revealed mucosa-associated lymphoid tissue (MALT) lymphoma. Lymphatic tissue develops in the submucosal layer in the large intestine, therefore it is sometimes dificult to diagnose colonic MALT lymphoma by biopsy. We have reported a case of cecal MALT lymphoma, diagnosed by CSP.
