Giant myxoid liposarcoma of the stomach: Report of a case
Liposarcoma is one of the most common soft tissue sarcomas in adults, but liposarcoma arising primarily from the stomach is very rare.

A 56-year-old man was referred to our hospital with abdominal distension and discomfort. A computed tomography scan showed a huge mass located between the stomach and transverse colon. The preliminary differential diagnoses were sarcoma with a mucinous component, gastrointestinal stromal tumor, lymphangioma, and mesenteric cyst. Upper and lower endoscopy was not performed because the patient declined.

The patient underwent surgical resection, and the tumor was completely removed. Macroscopic examination revealed a 39- × 26- × 20-cm tumor weighing 13,000 g. On histological examination, the tumor was diagnosed as a myxoid liposarcoma in the gastric submucosa. The patient was still doing well 2 years postoperatively.
