Laryngeal oncocytic cyst presenting with an acute onset of stridor.

Oncocytic lesions of the larynx are rare. When they have occurred, their presentation has been varied; these tumors may be completely asymptomatic and discovered incidentally, but more commonly they present with voice alteration. We report a case of an oncocytic cyst in a patient who presented with an acute onset of stridor. We also discuss the clinical manifestations and management of laryngeal oncocytic cyst and its relevant pathologic features.
