Objective. The occurrence of a rare alveolar rhabdomyosarcoma in a 16-
year old girl seems worth of a case report. Observation. A large multi
nodular tumor developed on the buttocks and the external genitalia; sy
stemic symptoms and metastases of lymph nodes and skin occurred very s
oon and the disease had a lethal outcome within 16 months. A temporary
regression was observed after polychemotherapy with daunorubicine, vi
ncritine and 5-fluoro-uracile. Comments. In children the rhabdomyosarc
oma is the most frequent sarcoma of soft tissues; the poor prognosis o
f the alveolar type is assessed by the case of this 16-year old girl;
this tumor may progress as a systemic disease and present as a leukemi
a with rapid impairment of general health, enlargement of lymph nodes,
cutaneous nodules and anemia.
