Abstract

The glomus tumor or glomangioma is an uncommon benign tumor that arises from the modified smooth muscle cells of the glomus body, a neuromyoarterial receptor sensitive to temperature, that regulates arterial flow. It is most commonly found in the skin particularly in the nailbeds or fingertips, but approximately 70 cases described in the stomach. The author experienced a glomus tumor of the stomach was found in a 43 year old female patient who had discomfort in upper abdomen for 40 days. Clinically, this uncommon gastric tumor mimics most of the benign and malignant lesions of the stomach and the most important aspect of this tumor is its histologic identification and differentiation from the more common gastric lesion. Microscopically the tumor was composed of cellular lobules of various sizes separately by irregular fibrous and muscular trabeculae. Ultrastructural study showed basal lamina, pinocytotic vesicles and numerous subplaomalemmal plaque.
