Abstract

Primary colorectal lymphoma accounts for only 0.2~.65% of large intestinal malignancies. Mucosa-associated lymphoid tissue lymphoma in the rectum is very rare. We report the case of a 73-year-old woman with morphologic and immunophenotypic findings consistent with mucosa-associated lymphoid tissue lymphoma of the rectum. The woman complained of consistent bloody diarrhea and recently developed abdominal pain, febrile and chilling sensation. Ultrasonography of upper abdomen detected multiple stones within the gallbladder and the gallbladder was resected using laparoscopic surgery. An ulcerative polypoid mass in the rectum was detected by colonoscopy and computerized tomography of abdomen. Microscopic and immunohistochemical studies showed a diagnosis of mucosa-associated lymphoid tissue (MALT) lymphoma. This patient was consulted to the department of radiotherapy because of poor general condition and old age. Chemotherapy was not performed. She was followed up with no relapse of the lesions during 7 months after the diagnosis.
