A Case of Laryngeal Granular Cell Tumor

Granular cell tumors can occur at any body site. While in about a half of the cases, they arise in the head and neck region, occurrence in the larynx is rare. Based on their characteristic immunohistochemical staining patterns, granular cell tumors are thought to arise from Schwann cells. In all but a small percentage of cases, the tumors are benign. Multiple tumors in the body are seen in 10%-14% of cases. Herein, we report a case of granular cell tumor of the vocal cord.
