Colorectal Lymphoma

Lymphoma of the colon and rectum is rare clinical entity that comprises only 0.2% of large intestinal malignancies. The gastrointestinal tract is the most common site of extranodal lymphoma involvement. Among colorectal lymphoma, over 70% are found proximal to the hepatic flexure. The most common presenting symptoms are abdominal pain and weight loss, which are non-specific findings. Lower GI bleeding and perforation are rare. Diffuse large B-cell lymphoma is the most common histologic subtype followed by mucosa-associated lymphoid tissue (MALT ) lymphoma.
