ABSTRACT Glomus tumors are rare, generally benign tumors that originate from the glomus body, a structure involved in thermoregulation. They are commonly found under the nails or in peripheral soft tissue and rarely in the gastrointestinal tract. We report the case of a 75-year-old woman with a history of non-Hodgkin lymphoma and atrial fibrillation who was found to have a gastric glomus tumor during an evaluation of iron deficiency anemia. We present a detailed description of the differential diagnosis, histopathologic findings, red flag signs for malignant transformation, and surveillance recommendations for patients diagnosed with gastric glomus tumor.
