A Case of Neurilemmoma of the Posterior Wall of the Hypopharynx / 대한이비인후과학회지

ABSTRACT

Neurilemmoma is a relatively rare benign tumor which may be derived from nerve sheath of the peripheral and cranial nerve. And it is a characteristically solitary and well-encapsulated mass. About 25% of neurilemmoma occurs in the head and neck region and therefore the vestibular nerve is most frequently involved. Neurilemmoma arising in the posterior wall of the hypopharynx is thus quite rare. In this study, we report a recent encounter with a case of neurilemmoma originating from the posterior wall of the hypopharynx in a 44 year old male patient. The tumor was successfully removed by lateral pharyngotomy under general anesthesia.
