Glomus tumors are maturely organized proliferations of glomus cells and vascular channels. Such tumors are rare in the stomach, and only two cases have been reported in Korea. Because specific clinical or radiologic features are not associated with the glomus tumor, it can be recognized only by histologic characteristics. Although available data are inadequate for determining the histogenesis of this tumor, it may represent a hamartoma rather than a neoplastic disease. The treatment of choice is local resection. In frozen sections, it may be misidentified as a carcinoid tumor, leading to more extensive surgery than required for cure. We report a case of a glomus tumor of the stomach in a 30-year-old female patient who was operated on, and we present a review of the literature on this subject.
