Leiomyoblastoma of the stomach: endoscopic treatment.

Since 1960, about 250 cases of leiomyoblastoma of the stomach have been reported. The diagnosis was always made after surgical resection or necropsy. We report the first case of gastric leiomyoblastoma successfully treated by endoscopic resection, in a 76-year-old woman presenting with upper gastrointestinal bleeding. This therapeutic procedure would seem to be the one of choice, in view of the age of the patient, the limited size and the pedunculated form of the tumor. Endoscopic follow-up should be instituted since local recurrence of the tumor and distal metastases have been reported.
