Fetal rhabdomyoma of the lower extremity.

We report a rare case of cellular fetal rhabdomyoma in a 9-year-old male, in the unusual location of right lower thigh. These tumors are more common in the head and neck region; and this case the second such case to be reported in the thigh. Fetal rhabdomyoma is a benign tumor of the skeletal muscle, showing varying degrees of skeletal muscle maturation. The present report discusses the histopathological features, the differential diagnosis and the importance of making the correct diagnosis for proper management of this rare entity.
