Abstract:

Glomus tumors are rare, usually bening mesenchmyal tumors arising from the glomus corpuscles. The majority of the glomus tumors are located in the distal extremities, in the subungual region, but can also be seen in different localizations including the trachea, kidney, lungs, uterus, vagina and gastrointestinal tract. Stomach localization is very rare. In this article, diagnostic problems of a gastric glomus tumor are discussed in the light of the literature. A 62-year-old female patient who admitted to general surgery with epigastric pain. Endoscopic examination revealed a 3cm submucosal lesion in the antrum localization and wedge resection was performed. Histopathological examination revealed a small, monotonous tumor with round nuclei around the hyalinizing vessels. Immunohistochemically, SMA, calponin, MSA positive; cytokeratin, S-100, synaptophysin, chromogranin A and NSE were negative. Our case was diagnosed as Glomus tumor. Glomus tumors should be considered in the differential diagnosis of the gastric nodular tumoral lesions. Although gastric glomus tumor is usually benign, malign behavior cannot be excluded. All cases must be followed up.
