Few reports of cases of adenomyomas of the stomach are found in the literature. Many of the references to this condition are included in discussions of other closely related heterotopias of the digestive tract, such as accessory islands of pancreatic tissue. Although most of these heterotopias are only of academic interest, adenomyomas have a definite clinical importance because of their closer approach to a neoplastic type of growth, the actual presence of a tumor mass, the similarity in appearance to carcinoma at operation and the possibility of clinical symptoms.

Microscopically, all showed alveoli of various types surrounded by smooth muscle bundles. Some of the alveoli were relatively undifferentiated, others resembled Brunner's glands, and still others were similar to pancreatic
