Abstract
Glomus tumors originate from smooth muscle cells implicated in the thermoregulation within the glomus body, an arteriovenous anastomosis located in the dermis [1]. Therefore, the majority of glomus tumors are found in fingernails, hands and feet [2]. Gastric glomus tumors are rare [2]; the antrum being the most frequent location in the stomach [3]. Those tumors are usually benign, but few cases of malignant gastric glomus tumors are described [1]. Neither radiologic nor endoscopic findings are typical of gastric glomus neoplasms [3]. Thus, the immunohistochemical study of a tumor sample is needed to make the diagnosis [3]. We report a case of gastric glomus tumor followed by a discussion about the presentation and the diagnosis challenge of this lesion.
