The gastrointestinal tract lipomas are a rare, benign, slow-growth condition and can be a diagnostic challenge, they are more frequent in the colon. The gastric lipoma occurs in fewer than 5% of cases, and represents less than 1% of all gastric tumors, usually their finding is incidental and the initial presentation may be obstruction, bleeding and intussusception. The purpose of presenting this case for its rarity, the few symptoms that the patient present and collect the most current information about the diagnosis and treatment. We report the case of a 59 years-old male patient who after having suffered acute pancreatitis a tomography control was made looking for complications it found a pylorus-duodenal intussusception, an endoscopy was performed and a tumor about 6 cm was found and biopsies without confirm diagnosis, so it was decided to perform a partial gastrectomy, histopathology study confirmed the diagnosis of gastric lipoma as well as disease free margins. Was maintained with adequate postoperative evolution currently asymptomatic. The gastric lipoma is a rare benign entity that can mimic a malignancy, in our case an incidental finding which was managed by partial gastrectomy with satisfactory postoperative results.
