ABSTRACT
Granular cell tumors (GCTs) are uncommon neoplasm. They can originate in any part of the body. The most common sites of origin are in the head and neck, while the larynx is a relatively uncommon location. Patients affected with a laryngeal GCT typically present with persistent hoarseness, stridor, hemoptysis, dysphagia, and otalgia but, the tumor may be asymptomatic. Care must be taken to differentiate this lesion from others due to the presence of pseudo-epitheliomatous hyperplasia which overlies the GCT and may occasionally mimic squamous cell carcinoma. Therefore, a confirmative diagnosis should be made histopathologically and should be supported by immunohistochemical staining. These tumors are treated by complete surgical resection. Examining the complete removal of the tumor through securing a negative free margin is considered to be a consequential procedure. We experienced a 64-yr-old man with a laryngeal granular cell tumor involving the right true vocal cord. He was treated by surgical resection under a fine dissection laryngomicroscope. Here we present this case and a review of literature.
