Résumé
A gastric lipoma is a rare entity and accounts for 2–3% of all benign gastric lesions. It is a diagnostic challenge. We present a case of a 35-year-old male who presented with intermittent attacks of pain in abdomen, vomiting, and dyspepsia. Upper gastrointestinal (GI) endoscopy showed a polypoidal lesion in the antrum prolapsing into the duodenum. Contrast-enhanced computed tomography abdomen showed a 5 cm × 3 cm × 3 cm, oval, smooth fat density lesion in the posterior wall of the antrum near the pylorus confirming the diagnosis of submucosal gastric lipoma with gastric outlet obstruction. Laparoscopic gastrostomy with removal of submucosal lipoma was done with uneventful post-operative recovery. The patient gained 10 kg weight after 18 months of follow-up without any GI symptoms. In conclusion, gastric lipomas are rare benign tumors of the stomach which may mimic malignancy.
