Abstract
RATIONALE: Glomus tumors (GTs) are a rare disorder originating from the glomus of the anastomoses of small arteries, usually occurring in the subungual region of the fingertips or toes and seldom occurring in the stomach. We unintentionally found a case of a gastric glomus tumor (GGT) without any upper abdominal discomfort. The diagnosis of this disease was mainly by immunohistochemistry. PATIENT CONCERNS: The patient presented to our hospital with intermittent right abdominal pain for 1 month. Abdominal computed tomography showed a nodular enhancement lesion in the gastric antrum. DIAGNOSES: The patient was diagnosed with an ileocecal tumor and a gastric stromal tumor. INTERVENTIONS: Surgical resection of the ileocecal and gastric tumors was performed. OUTCOMES: Pathologic examination of gastric masses revealed GT. The operation was effective, and the patient was discharged from our hospital 7 days after surgery. Upon follow-up at 3 months, the patient was asymptomatic. LESSONS: GTs are submucosal tumors rarely found in the stomach. Surgical resection is a good choice of treatment. The GGT lacked specific clinical and imaging features, and immunohistochemistry was essential in the diagnosis of GGT.
