title: Orbital-conjunctival glomangiomas involving two ocular rectus muscles.
abstract: OBJECTIVE
  To report two glomangiomas in one orbit, each isolated to a rectus muscle.
  
  
  METHODS
  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.
