Abstract
Glomus tumor of the stomach is a rare submucosal mesenchymal tumor. The present study reports a patient with gastric glomus tumor treated by laparoscopic distal gastrectomy. A 39‑year‑old male was referred to Kochi Medical School Hospital for examination of a gastric submucosal tumor (SMT) initially diagnosed following a medical check‑up. Esophagogastroduodenoscopy revealed a solitary, well‑defined, submucosal lesion in the antrum of the stomach. Endoscopic ultrasonography (EUS) revealed a hypoechoic solid mass primarily connected to the gastric muscular layer. Abdominal contrast‑enhanced computed tomography confirmed a 1.5 cm, well‑defined mass lesion demonstrating homogeneous strong enhancement in the gastric antrum. Subsequent EUS‑guided fine‑needle aspiration produced a clinical diagnosis of neuroendocrine neoplasm and the patient underwent laparoscopic distal gastrectomy with regional lymph node dissection. Histopathology revealed solid proliferation of round, α‑smooth muscle actin‑immunopositive tumor cells with dilated vessels lined by endothelial cells without atypia, prompting a diagnosis of gastric glomus tumor. To the best of our knowledge, this is the seventh case of gastric glomus tumor treated by laparoscopy reported in English literature. The present case suggested that glomus tumor should be considered in the differential diagnosis for SMT of the stomach.
