title: Highly cellular leiomyoma mimics a malignant small round-cell tumor: a diagnostic dilemma on frozen sections.
abstract: OBJECTIVE
  Cellular leiomyoma is characterized by significantly increased cellularity and may mimic malignant tumors. Our aim was to differentiate these from other malignant small round-cell tumors.
  
  
  METHODS
  We report a case of cellular leiomyoma that mimicked a malignant small round-cell tumor upon frozen section examination.
  
  
  CONCLUSIONS
  Pathologists should be aware that highly cellular leiomyomas can mimic malignant tumors especially on frozen section analysis.
