Highly cellular leiomyoma mimics a malignant small round-cell tumor: a diagnostic dilemma on frozen sections.
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.
