Gastric Polypoid Lymphoma of Mucosa-Associated Lymphoid Tissue Type

A polypoid, or submucosal tumor-like, presentation of Mucosa-Associated Lymphoid Tissue (MALT) lymphoma is relatively rare, while correct clinical and histopathological diagnoses of such cases are important for patients in order to avoid unnecessary advanced surgical intervention. We reported an 88-year-old gentleman with a low-stage MALT lymphoma, presenting with a polypoid subepithelial tumor on endoscopy. The present case would bring attention to both clinicians and pathologists that gastric MALT lymphoma could present as a long-standing, polypoid subepithelial tumor, and the patient should be managed conservatively with medical treatment or localized radiotherapy
