Złośliwe i niezłośliwe guzy chrzęstne krtani

6 patients manifested hoarseness, 5 dyspnea, 3 dysphagia, 1 neck mass as the first symptom. In laryngoscopy a tumour with intact mucosa was situated in subglottis - 5 patients, in supraglottis - 2 patients and in half of the larynx with fixation - 4 patients. The majority of tumours involved the cricoid cartilage - in 9 cases, the rest arytenoid and epiglottic cartilage. The histopathology diagnosis were given after surgery, only in one case after biopsy. There were 7 patients with chondrosarcoma and four with chondroma. We did not observe lymph node or distant metastases. All patients were treated surgically. Follow-up of patients with chondrosarcoma were 5 to 17 years without recurrence. However, two recurrences of chondroma appeared to be chondrosarcomas and required laryngectomy.
