title: Hemorrhagic complication in an unsuspected macular choroidal melanoma.
abstract: OBJECTIVE
  To report a rare presentation of a hemorrhagic complication in a patient with unsuspected macular choroidal melanoma.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  A 32-year-old Chinese woman presented with disturbance of her left central vision. A hemorrhagic mass at the macula was noticed that was evacuated by submacular surgery.
  
  
  RESULTS
  The mass expanded rapidly into a mushroom configuration after surgery. Fine-needle aspiration confirmed the diagnosis of malignant choroidal melanoma, and enucleation followed. Histology demonstrated moderately large epithelioid tumor cells with prominent nucleoli. The sclera was intact, and the optic nerve was not involved. The patient has been followed for 5 years without signs of local recurrence or metastasis.
  
  
  CONCLUSIONS
  We should be alert for atypical presentations of choroidal melanoma. Unnecessary or inadvertent surgical intervention may induce tumor growth and subsequent local spread or metastasis.
