Rectal lymphoma: report of a rare case and review of literature

Acta Med Iran. 2014 May 25;52(10):791-4.


Colorectal lymphoma is an extremely rare disease, representing less than 0.5% of all primary colorectal neoplasms. The disease is usually diagnosed in the advanced stages because of its primary non-specific symptoms. The most common involved site is cecum followed by rectum and ascending colon. Diffuse large B-cell lymphoma is a more frequent subtype. Although surgical resection is often technically feasible, optimal therapy for a colorectal lymphoma, especially rectal lymphoma, has not yet been identified. The authors describe a patient with the primary rectal lymphoma, high-grade features and complete response to chemotherapy.
