[Atypical sarcomas localized within a head and neck in children]

Seven children treated surgically because of non-rhabdomyosarcomatous soft tissue sarcoma (NRSTS) localized extrameningeally on the head and neck were presented. Three of the patients were operated on haemangiopericytoma, two--fibrosarcoma, one child--neurofibrosarcoma and one--liposarcoma. The pre- and postoperative TNM classification was employed as a staging system. The surgical resectability--R was used to establish tumour margins. Four patients (two with fibrosarcoma and two with haemangiopericytoma) survived free of disease. The influence of the complete surgical resection on the outcome of the head and neck extrameningeal NRSTS was proved.
