Huge Lipoma in Gastric Body Presenting with Hypovolemic Shock: Report of a Case

Huge gastric lipomas rarely manifest as hypovolemic shock. We report a 69-year-old man who was admitted to our emergency room because of a two-day history of tarry stool. Emergency upper gastrointestinal endoscope revealed two masses measuring 9 cm×7 cm×5 cm and 1.5×cm×1.5 cm×1.5 cm, respectively, with smooth surface and ulcerative changes at the base, located on the posterior wall of the stomach body. Gastrointestinal stromal tumor or malignancy was suspected pre-operatively. Open surgery with subtotal gastrectomy + Billroth II gastrojejunostomy was performed because the possibility of rebleeding and malignant could not be rule out. Pathological examination disclosed a bleeding ulcerated submucosal lipoma. Herein, we report a case of a huge gastric lipoma presenting as hemorrhagic shock and review the literature regarding this relatively rare tumor.
