title: Ciliary body schwannoma successfully treated by local resection.
abstract: BACKGROUND
  Schwannoma arising from the ciliary body is a rare intraocular neoplasm, and most cases previously reported were diagnosed histopathologically after eyeball enucleation because of a diagnosis of ciliary body melanoma.
  
  
  METHODS
  A case of ciliary body schwannoma was dissected locally.
  
  
  METHODS
  A 19-year-old woman was referred to us with a diagnosis of iris cyst. Local resection of the tumor was performed because of deteriorated visual acuity caused by displacement of the lens. In histopathological analysis, the encapsulated tumor showed a proliferation of the spindle cells with no atypia, and in immunohistochemical analysis, tumor cells were positive for S-100 protein; these findings were compatible with schwannoma. Visual acuity improved postoperatively, and no complications or recurrence have been observed in the 4 years since surgery.
  
  
  CONCLUSIONS
  Schwannoma should be considered in the differential diagnosis of a ciliary body tumor.
