[Diagnosis and evaluation of cervico-facial cancers in children].

Malignant neoplasia of head and neck in children are mostly embryonal sarcoma and non Hodkgin's lymphomata. Squamous-sell carcinomas are only 10%. The main locations are in nasopharynx and paranasal sinuses. Symptoms are corelated with location of the primary. Treatment depends of the pathologic type. Combination of chemotherapy and radiotherapy, and sometimes surgery, yield now more cured patients, especially in embryonal sarcoma.
