[Granular cell tumour of the larynx--report of two cases]. / Guz abrikosowa krtani--analiza dwóch przypadków.

Granular cell tumour (Abrikosov tumour) of the larynx is an uncommon laryngeal tumour. We report two cases of this rare type of tumor, which were diagnosed and treated at the Department of Otolaryngology of District Hospital in Zamosc in the period 1999-2005. The tumours were detected in two adult men. In the first case (29 years old patient) the tumour was located next to the right arytenoid. The tumour was removed by microlaryngoscopy. In the second case (55 years old patient) the tumour involved half right vocal fold from the posterior commissure. It was removed by laryngofissurae. Both tumours have not recurred after a 5 years follow-up and are still under observation.
