A CASE OF COLONIC MUCOSA-ASSOCIATED LYMPHOID TISSUE (MALT) LYMPHOMA WITH REGIONAL LYMPH NODES AND STOMACH INVOLVEMENT TREATED WITH RESECTION OF COLON AND CHEMOTHERAPY

Abstract

A 67-year-old woman presented to our hospital because of bloody stools. Colonoscopy revealed an elevated lesion with erosion in the transverse colon. A biopsy specimen showed mucosa-associated lymphoid tissue (MALT) lymphoma on histological examination. Since eradication therapy for Helicobacter pylori failed to reduce the size of the tumor, it was surgically resected together with the regional lymph nodes. Histological examination of the sampled specimen showed involvement of some lymph nodes with the lymphoma. After resection of the transverse colon, MALT lymphoma was also found in the stomach by biopsy. The patient therefore underwent treatment with chemotherapy, resulting in remission of the lymphoma.
