PURPOSE: To report two glomangiomas in one orbit, each isolated to a rectus muscle. DESIGN: Clinicopathologic correlation. METHODS: A 12-year-old boy developed two separate vascular tumors, near the insertions of the medial rectus and superior rectus muscles, respectively. A biopsy of one tumor was studied by light microscopy and immunohistochemistry. RESULTS: Histopathology revealed blood vessels surrounded by cuboidal cells characteristic of glomangioma. The cells showed immunoreactivity for smooth muscle actin and vimentin, supporting the diagnosis. CONCLUSIONS: Glomangioma can involve the rectus muscles in the conjunctiva and orbit, and should be considered in differential diagnosis of vascular tumors in the ocular region.
