title: MYOMELANOCYTIC CHOROIDAL TUMOR: Cytopathologic Diagnosis.
abstract: OBJECTIVE
  Establishing the correct diagnosis of a growing choroidal tumor can be difficult.
  
  
  METHODS
  Clinical examination and ultrasound of a patient followed for what was thought to be a uveal melanoma. Fine-needle biopsy established the correct diagnosis.
  
  
  RESULTS
  We demonstrate that fine-needle biopsy can correctly identify a very rare tumor, a myomelanocytic neoplasm.
  
  
  CONCLUSIONS
  Myomelanocytic choroidal tumors can be diagnosed on fine-needle biopsy.
