Primary colorectal lymphoma is a rare disease that accounts for 0.16% of colorectal malignancies. Treatments include surgical intervention with or without chemotherapy. Outcome of this intervention among the Chinese population are lacking. Perforation resulting from chemotherapy may need further exploration. A retrospective review of patient records was performed among those who were diagnosed with colorectal malignancy in a single center from January 1998 to June 2009. Ten patients met Dawson's diagnostic criteria for primary colorectal lymphoma [0.66% (10/1516) of all colorectal malignancies]. The male-to-female ratio was 9:1, and median age at diagnosis was 76 years. The most common site was the cecum (n = 5). B-cell lymphoma was present in eight patients. Seven patients underwent surgical intervention. The median follow-up of all patients was 16.5 months. Median survival was 17 months and 13 months in the surgical and chemotherapy group, respectively. Primary colonic lymphoma is a rare disease. Surgical intervention appeared to be superior to chemotherapy alone, but the findings were limited by the small number of patients in this study. Whether surgery or chemotherapy should be offered first remains unknown and requires further research.

Primary colonic lymphoma is a rare tumor accounting for 0.1%-0.5% of all colorectal malignancies. We describe a 63-year-old man whose initial presentation was altered mental status due to hypercalcemia. Physical examination revealed a hard, right-sided abdominal mass. Abdominal computed tomography showed a mass in the ascending colon, which on further evaluation with colonoscopy and biopsy was diagnosed as diffuse large B-cell lymphoma. A diagnosis of primary colonic lymphoma was made based on the Dawson criteria, after ruling out any extracolonic involvement. Workup for hypercalcemia showed elevated calcitriol levels, which is a paraneoplastic manifestation of the lymphoma.
