Core Tip

Core Tip: Liposarcoma is uncommon in the gastrointestinal tract and rarely encountered in the stomach. Furthermore, the dedifferentiated histologic subtype has not been previously reported in the stomach in the English literature. We experienced a case of a small (1.7 cm) primary gastric dedifferentiated liposarcoma, which was resected endoscopically. This report cautions that if a diagnosis of submucosal tumor is uncertain, the use of aggressive techniques, including endoscopic resection, should be considered.
