Gastrointestinal Follicular Lymphoma of the Cecum Treated via Endoscopic Full-Thickness Resection.

ABSTRACT

Gastrointestinal follicular lymphoma (GI-FL) is an uncommon non-Hodgkin lymphoma that affects the gastrointestinal tract. It typically occurs within the duodenum with the appearance of multiple nodules. Treatment options, depending on stage and grade of the tumor, include aggressive chemotherapy, immunotherapy, radiotherapy, surgical or endoscopic resection, or simply monitoring as focal disease may be indolent. We present a rare case of a GI-FL presenting as a solitary lesion within the cecum treated via endoscopic full-thickness resection using the Ovesco full-thickness resection device. This case demonstrates the effectiveness of endoscopic full-thickness resection in treating small GI-FL in the colon.
