Liposarcoma is the most common soft tissue sarcoma and accounts for 15-20% of all mesenchymal malignancy. The tumor occurs most frequently in the limbs, retroperitoneum and rarely has a visceral location.

Liposarcoma of the stomach is extremely rare (37 case reported worldwide up to 2018). The origin of gastric liposarcomas is likely the proliferation of undifferentiated mesenchymal cells within the submucosa and the tunica muscularis layer of the stomach. Gastric liposarcomas are characterized by an exophytic growth that adheres to the gastric wall, and the typical location of gastric liposarcomas is the antrum (38.8%, Kang 2018).

Of the 37 cases described six patients died of the disease. Mortality is usually in cases of dedifferentiated, myxoid, pleomorphic and mixed type liposarcoma.
