Abstract
This is a report of an exceptional case of hemangiopericytoma of the larynx, which occurred in a 50-yr old male patient. Histological examination of biopsy fragments allowed the correct diagnosis, later confirmed at autopsy, to be made. From a comprehensive review of the world literature on hemangiopericytomas, it appears that cases of indisputable well-documented laryngeal occurrence of the neoplasm amount to 2 only, including the present case. The morphological pattern, histogenesis, biological behavior and therapy of the tumor, as well as differential diagnosis from other lesions, are discussed.
