Unusual leiomyoblastoma of the stomach.

Only about 250 cases of benign gastric leiomyoblastoma of the stomach have been reported. Most occur in the smooth muscle of the antrum, and may be intramural, intraluminal, or exogastric in position. A pedunculated gastric leiomyoblastoma occurs less frequently, and those containing radiographically identifiable calcifications are extremely rare.
