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.
