title: Report of two cases of ciliary body mesectodermal leiomyoma: unique expression of neural markers.
abstract: OBJECTIVE
  Mesectodermal leiomyoma of the ciliary body is a rare tumor with, to our knowledge, only 15 cases reported in the literature. It has a neural histopathologic appearance and a presumed origin from neural crest.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  Two cases of mesectodermal leiomyoma with histopathologic and immunohistochemical confirmation are reported.
  
  
  CONCLUSIONS
  For the second time, we were able to demonstrate expression of neural immunohistochemical markers in this tumor.
