title: Choroidal metastasis of mixed carcinoma of the parotid gland.
abstract: BACKGROUND
  A case of mixed carcinoma of the parotid gland (an epidermoid carcinoma located in a pleomorphic adenoma) metastatic to the choroid is presented. The histopathology of the tumor is discussed.
  
  
  METHODS
  A 65-year-old man was admitted complaining of blurred vision in his right eye for 1 day. He underwent parotidectomy for mixed carcinoma of the parotid gland (an epidermoid carcinoma located in a pleomorphic adenoma that was completely excised) 6 months before. Funduscopic examination showed a nasal retinal detachment, with gray-whitish, minimally elevated nodular choroidal lesions. Fluorescein angiography and contact B-scan ultrasonography confirmed the presence of an underlying mass.
  
  
  RESULTS
  The right eye was enucleated and an epidermoid infiltrating carcinoma was identified.
  
  
  CONCLUSIONS
  Metastatic tumors are the most common intraocular malignancies, and the choroid is by far the most common location for intraocular metastases. There are few cases reported of parotid tumors metastatic to the orbit. To the best of our knowledge, no histological examination of an ocular metastatic mixed carcinoma of the parotid gland has yet been reported.
