title: Glomus tumor in the stomach: A case report and review of the literature.
abstract: This study reports a rare case of a 47-year-old female with a gastric glomus tumor who was admitted with epigastralgia. Endoscopic ultrasound revealed a protrusion on the posterior wall of the gastric antrum. Enhanced computed tomography confirmed the presence of a 10-mm mass. The tumor was resected, and immunohistochemistry revealed the tumor to be positive for smooth muscle actin and collagen type IV, and negative for synaptophysin, chromogranin A, laminin, S-100, cluster of differentiation (CD)34, CD31, CD99, cytokeratin (AE1/AE3), desmin and epithelial membrane antigen. The proliferation marker Ki-67 was positive in <5% of tumor cell nuclei. The clinical procedures with a review of the literature are reported.
