Gastric Glomus Tumor Diagnosed by Upper Endoscopy

Gastric glomus tumors (GGTs) are benign tumors that typically occur in the submucosa of the gastric wall. Glomus tumors typically occur in the subungual region of the finger and rarely manifest in the stomach. Diagnosis is challenging as these tumors lack specific clinical features, radiographic findings, and endoscopic findings. In prior cases, endoscopic ultrasound with fine-needle aspiration has been utilized to make a pre-operative diagnosis. In our case, pathology from general endoscopy was consistent with a GGT. Thus, our patient was accurately diagnosed by esophagogastroduodenoscopy (EGD) with conventional biopsy.
