[Rare tumors of the larynx]

Six cases of the rarely encountered, advanced tumours of the larynx treated in ENT Clinic of Pomeranian Medical Academy in Szczecin are presented: chondroma, rhabdomyosarcoma, neurinoma, cylindroma and 2 cases of granular cell tumour. There were certain diagnostic difficulties in rhabdomyosarcoma and chondroma cases. The immunocytochemical investigations were of decisive significance in differential diagnosis of the larynx sarcoma. In the case of chondroma there were problems with biopsy taking the tense tissue of the tumour was compressing the subglottic space. The radiological examinations turned out to be very helpful in this case. All patients were treated by surgery, two of them with rhabdomyosarcoma and cylindroma were treated by irradiation too. Observation periods were from 0.5 to 10 years. The oncological and functional results in 4 cases after partial laryngectomies turned out to be satisfactory. All larynx activities were preserved. The patient with sarcoma of the larynx died 6 years after diagnosis of neoplasm. Finally author discuss diagnostic problems and methods of treatment.
