Abstract

Gastric adenocarcinoma presenting as a submucosal tumor (SMT) accounts to only 0.1% to 0.63%. A 56-year-old
Filipino male presenting with new onset melena underwent magnifying endoscopy, narrow-band imaging, endoscopic ultrasound, and computed tomography revealing a 2.5 cm x 2.0 cm polypoid SMT-like lesion at the fundus. Total gastrectomy with lymph node dissection and esophagojejunostomy was performed with histopathology showing adenocarcinoma. This suggests the need for different modalities to ensure the accuracy of diagnosis and the need for subsequent invasive treatments.
