Carcinoma of the colon : An unusual cause of prolonged fever

Solid tumors rarely present with fever. Among those that do, carcinoma of the colon has been infrequently reported as a primary cause of fever. This patient had carcinoma of the right colon with prolonged fever, but no evidence of infection or gastrointestinal symptoms. At surgical resection, a caecal adenocarcinoma was found with metastases to the mesentery and 10 of 40 lymph nodes. The patient's fever resolved after 3 days. The patient remained healthy during 8 years of follow-up. Right-sided colon cancer is not often considered in the complete evaluation of fever of undetermined cause.
