Rectal Lymphoma: Report of A Rare Case and Review of Literature

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 nonspecific 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.
