A case of depressed type mucosal cancer of the large intestine with converging mucosal folds is discussed . A 71‐year‐old female was admitted to our hospital with melena. A total colonoscopy revealed a type IIa + IIc lesion measuring 1. 5cm in diameter with converging mucosal folds in the transverse colon. An endoscopic biopsy revealed an adenocarcinoma. A diagnosis of submucosal carcinoma was made and a partial colectomy was performed. The resected specimen showed a type IIc + IIa cancer. Histologically, a well differentiated adenocarcinoma which was limited to the mucosa in association with fibrosis in the submucosa was revealed. The submucosal fibrosis was thought to be a cause of the converging mucosal folds .
