Abstract

|
Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is the most common form of primary extranodal lymphomas. In most cases, it is developed as multifocal and mucosal lesions, and its initial diagnosis is made by biopsy of suspicious lesions on endoscopy. However, when gastric MALT lymphoma afflict submucosal site without typical mucosal lesion, further procedures are necessary for diagnosis, such as endoscopic mucosal resection and endoscopic ultrasonography. We recently experienced two cases of submucosal tumor-like gastric MALT lymphoma. Both cases were without any mucosal lesion. One case was confirmed by endoscopic mucosal resection, and the latter was by wedge resection. Treatment modalities included endoscopic mucosal resection, surgery, H. pylori eradication, and/or chemotherapy. Both cases achieved complete remission until our 18 months’ and 16 months’ follow up.
