title: Mucolipidosis IV in an African American patient with new findings on electron microscopy.
abstract: OBJECTIVE
  We report an unusual case of mucolipidosis IV in a patient of African ancestry, with intracytoplasmic inclusions of the corneal endothelium found on electron microscopy.
  
  
  METHODS
  Clinical description with light and electron microscopy.
  
  
  RESULTS
  We describe a case of mucolipidosis IV diagnosed in a patient of African ancestry after penetrating keratoplasty. Electron microscopic evaluation revealed intracytoplasmic inclusions in both the corneal epithelium and endothelium.
  
  
  CONCLUSIONS
  The diagnosis of mucolipidosis in a patient of African ancestry is unusual, as this genetic disorder is found predominantly in individuals of Jewish descent. Corneal endothelial involvement in mucolipidosis IV has not previously been reported.
