[Glomus tumor of the stomach--a case report on a light and electron microscopic study].

This paper reports a case of glomus tumor of stomach from a male patient, 58 years old, with the chief complaint of nausea and vomiting after meal. This tumor was at the anterior wall of the antrum near the lesser curvature. By light microscopy, it was composed of glomus tumor cells and abundant blood vessels. Ultrastructurally, there were numerous filaments, dense bodies, adhesive bodies and pinocytotic vesicles in the cytoplasm. This kind of tumor should be differentiated from the leiomyoblastoma and hemangiopericytoma.
