A Case of Malignant Lymphoma of the Cecum Presented with Intussusception

Abstract

Malignant lymphoma of the colon is a rare disease and accounts for 0.1-0.7% of all malignant tumors of the colon. We report a case of malignant lymphoma of the colon in a 75-year-old male who underwent emergency surgery with a diagnosis of intussusception. The patient was admitted to our hospital complaining of abdominal pain and melena. On physical examination, his abdomen was hard with tenderness in the right lower quadrant, and his palpebral conjunctiva was anemic. Abdominal CT scan showed a tumor invaginated to the ascending colon. Emergency surgery was performed with a diagnosis of intussusception of the cecum tumor and severe melena. At laparotomy, the ileum was invaginated in the ascending colon with the cecum and the ascending colon. Thus, a right hemicolectomy was performed. Histological the tumor was diagnosed as diffuse large B-cell lymphoma (DLBCL). He was treated with chemotherapy postoperatively. No recurrence has occurred as of 15 months after the operation. We report this case with a review of the literature because intussusception in an adult due to malignant colon lymphoma is extremely rare.
