Polypoid Gastric Adenomyoma: A Rare Cause of Bleeding Treated With Polypectomy

Abstract

ABSTRACT Gastric adenomyoma is a rare tumor composed of smooth muscle fibers and glandular tissue. Usual presentations include nausea, bloating, and gastric outlet obstruction. We describe a case of a 60-year-old woman who presented with abdominal pain and melena. Endoscopy showed a 1.5 cm polyp in the stomach body that was resected using snare polypectomy. Biopsy showed glands mixed with fibromuscular tissue consistent with gastric adenomyoma. We conclude that gastric adenomyoma, although rare, may present as a bleeding polyp in the stomach body and may be treated with excisional polypectomy.
