Pathological examination revealed the nested growth of cells of a gastric glomus tumor. A: Microscopic examination shows numerous dilated, thin-walled vascular spaces surrounded by uniform glomus cells. The cells are round with sharp borders. (hematoxylin and eosin stain, magnification 200×). B: Prominent clear cell feature (hematoxylin and eosin stain, magnification 300×). C: Large hemangioma-like blood vessels inside the tumor. Tumor cells are clustered around the walls of blood vessels (hematoxylin and eosin stain, magnification 300×). D: The stroma shows diffuse mucoid degeneration (hematoxylin and eosin stain, magnification 300×).
