Mucoepidermoid carcinoma of the larynx is very rare, with only a few individual cases or studies in small patient groups reported in the literature. Treatment modalities for this type of carcinoma are not uniform; in addition, errors in the recognition and pathologic diagnosis are not uncommon. During the period 1991-2000, 771 cases of malignant laryngeal tumours were recorded and histologically verified at the University Department of Otorhinolaryngology and Cervicofacial Surgery, Zagreb University Hospital Centre, three of them were mucoepidermoid supraglottic carcinomas. The experience acquired in the treatment of these tumours is presented along with a review of the literature.
