title: Uveal melanoma in the peripheral choroid masquerading as chronic uveitis.
abstract: OBJECTIVE
  To describe a case of uveal melanoma in the peripheral choroid masquerading as chronic uveitis and to raise awareness about malignant masquerade syndromes.
  
  
  METHODS
  A 36-year-old Chinese woman presented from an outside ophthalmologist with a 6-month history of unilateral chronic uveitis unresponsive to medical therapy in the left eye. She was found to have a uveal melanoma in the retinal periphery and underwent successful enucleation of her left eye. The histopathological diagnosis confirmed the clinical diagnosis.
  
  
  CONCLUSIONS
  When uveal melanoma presents in an atypical way, the diagnosis is more difficult. This case highlights the uncommon presentations of malignant melanoma of the choroid. It provides valuable information on how peripheral uveal melanoma can present with clinical signs consistent with an anterior uveitis.
