title: Concomitant non-Hodgkin's lymphoma in colon and liver: report of a rare case and review of literature.
abstract: A 58-year-old male patient was admitted with right upper abdominal pain. Initial hematologic evaluation revealed mildly elevated serum carcinoembryonic antigen and carbohydrate antigen (CA) 19-9 tests, while an abdominal CT-scan showed a circumferential mass along the distal ascending colon and the right flexure of colon, simultaneously a liver lesion in segment 8 is considered metastases from colorectal. colonoscopic examination revealed a circumferential growth tumor in the right flexure of colon and the colonoscopy can not reach the proximal of the tumor. We performed a right hemihepatoectomy and a right hemicolectomy associated with loco-regional lymphadenectomy. Histological examination showed diffuse large B-cell lymphomas in resected right colon as well as liver tumors. The patient received six courses of chemotherapy with CHOP-based regimens. At 14-month follow-up before this report, the patient is still alive and free of disease.
