title: Acute monolateral proptosis and orbital myositis in a patient with discoid lupus erythematosus: a case report.
abstract: BACKGROUND
  Discoid lupus erythematosus may lead to significant orbital inflammation syndrome. Ocular manifestations related to discoid lupus erythematosus are uncommon and few cases of eye inflammation are reported.
  
  
  METHODS
  A 37-year-old Caucasian woman with 5-year history of discoid lupus erythematosus presented with exophthalmos, periorbital pain and blurred vision in her right eye. Orbital computed tomography and laboratory tests were performed. Computed tomography imaging revealed an enlargement of the right medial rectus muscle. Thyroid eye disease and orbital cellulites were excluded. Corticosteroid treatment completely resolved the symptoms.
  
  
  CONCLUSIONS
  This is the first case of orbital myositis in a patient with discoid lupus erythematosus presenting with acute proptosis, diplopia and single extraocular muscle involvement.
