Endoscopic mucosal resection and cure for rectal mucosa-associated lymphoid tissue lymphoma.

We present a case of negative rectal mucosa-associated lymphoid tissue (MALT) lymphoma found on colonoscopy done for colorectal cancer screening. The lesion was successfully removed with endoscopic mucosal resection alone, without concomitant antibacterial treatment. On surveillance exams, the patient has had a 5-year disease-free survival. While prior reports highlight use of multiple modalities, this is the only case we are aware of in which treatment with endoscopic mucosal resection alone without antimicrobial therapy led to disease-free survival at 5 years.
