Core Tip

Core Tip: Colorectal involvement of Mucosa-associated lymphoid tissue (MALT) lymphoma occurs rarely and the management of colorectal MALT lymphoma are not well established yet. We report a rare case of colorectal MALT lymphoma treated with endoscopic resection alone. To date, only six cases of primary colorectal MALT lymphomas treated with endoscopic resection alone, including our patient, have been documented in the medical literature. Among the reported cases, there was no recurrence during follow-up. These results of our case and previous reports suggest that endoscopic resection alone may be a feasible and safe treatment for primary colorectal MALT lymphoma and allows organ preservation.
