Granular Cell Tumors of the Larynx: A Clinicopathologic Study of Five Patients.

Granular cell tumors (GCT) are uncommon neoplasms that may involve the larynx. Patients affected with a laryngeal GCT usually complain of dysphonia. When they involve the larynx, these tumors have predilection for the posterior half of the vocal cords. Between 2006 and 2018, we have experienced five cases of GCT involving the right true vocal cord. They were diagnosed and successfully treated with microsurgical resection. Here we present this 5-case series and a retrospective review of literature.
