Endoscopic Dissolution of Gastric Lipoma with Argon Plasma Coagulation.

A 47-year-old patient presented from outside the hospital for evaluation of iron deficiency anemia (IDA). The endoscopic workup suggested a gastric antral subepithelial lesion with an overlying arteriovenous malformation (AVM). Endoscopic ultrasound (EUS) revealed the lesion to be a lipoma. Given the patient's anemia and blood transfusion requirements, the AVM was treated with argon plasma coagulation (APC). During this treatment, desiccation of fat was noted with a significant decrease in the size of the subepithelial lesion (the gastric lipoma). While the APC therapy was intended for management of the overlying AVM, it resulted in the partial dissolution of the gastric lipoma, proving to be a potential diagnostic and therapeutic tool.
