Botryoid rhabdomyosarcoma of vagina--two case reports.

Botryoid rhabdomyosarcoma, previously considered a type of embryonal rhabdomyosarcoma, has clinicopathological features distinctive enough to warrant its classification as a separate entity. It almost always occurs in children under 5 years of age. Two cases of botryoid rhabdomyosarcoma are reported here because of their relative rarity.
