Glomus tumor (glomus cell tumor) is a rare, often benign neoplasm, which is, in most cases, seen as a solitary bluish nodule involving the nail beds. Solid glomus tumor, glomangioma, and glomangiomyoma are the three main histopathological variants. In this case report, we present the rarest subtype of a glomus tumor, glomangiomyoma, in an atypical location: the stomach. A 45-year-old female from Syria presented to the clinic with severe dizziness and left epigastric abdominal pain accompanied by melena. We performed a thorough clinical study, laboratory workup, upper gastrointestinal endoscopy, endoscopic ultrasound, CT scan, as well as macroscopic and microscopic histologic examination of the surgical specimen, in addition to the immunohistochemical staining. Although rare, gastric glomangiomyoma was diagnosed and a 4.5 × 3 × 3 cm soft tissue mass was resected from the gastric antrum, and no clinical or endoscopic evidence of recurrence was observed for the follow-up duration of 4 years. Undiagnosed gastric lesions with unexplained symptoms should be further investigated and not be disregarded immediately. To the best of our knowledge, this is only the second report of an instance of gastric glomangiomyoma.
