Successful Endoscopic Resection of Mucosa-Associated Lymphoid Tissue Lymphoma of the Colon.

Mucosa-associated lymphoid tissue lymphomas are the most common form of primary malignant gastrointestinal lymphoma. Although typically found in the stomach, extragastric locations have been described, in rare cases, the colon. The optimal management of these neoplasms remains uncertain and limited largely to small retrospective series or case reports. We report a patient with a colonic mucosa-associated lymphoid tissue lymphoma identified during a routine screening colonoscopy which was removed endoscopically without any adjuvant antimicrobial therapy, chemotherapy, or radiation therapy. She remained disease-free after the 1-year follow-up, providing support to potential endoscopic therapy in appropriately selected patients.
