title: Pleomorphic  rhabdomyosarcoma of the larynx. A case report and review of the literature.
abstract: A case of pleomorphic rhabdomyosarcoma of the larynx occurring in a 33-year-old male is reported. The clinical and histopathological aspects of this undoubtedly rare neoplasm are described. After a quick review of the most important classifications of rhabdomyosarcoma so far made, the authors suggest a division into two basic groups, i.e. pleomorphic and fetal rhabdomyosarcoma, while the botryoid sarcoma and the alveolar rhabdomyosarcoma should be considered only as two subgroups of fetal rhabdomyosarcoma. From a comprehensive review of world literature on the subject, the well-documented cases up to now described are only seven, including the authors. The present case is the third one after the instances of pleomorphic rhabdomyosarcoma reported by Filipo and Crifo (1964 and by Rodriquez and Ziskind (1970).
