A Case Report: Primary Mucosa-Associated Lymphoid Tissue Lymphoma of the Rectum

Abstract

A 75-year-old woman was admitted to our hospital because of occult blood in the stool. She had undergone resection of Isp type polyp (diameter 2.0 cm) in the rectum under colonoscopy. Histopathological diagnosis of the resected polyp was mucosa-associated lymphoid tissue lymphoma (MALT). Nine months after the initial resection, the tumor recurred in the same area. So the tumor was resected again. Because the tumor had remained, transsacral sleeve resection of the rectum was performed. It is suggested that partial resection of the rectum is required for MALT lymphoma.
