LARYNGEAL GRANULAR CELL TUMOR; RARE LOCATION

Granular cell tumors (GCTs) are relatively uncommon benign laryngeal lesions thought to originate from schwann cells. They were first described by Abrikossoff in 1926 and also known as Abrikossof’s tumor (1). The larynx is an uncommon location for these tumors, accounting for approximately 3 % of adult cases. They located most commonly on the posterior two thirds of the vocal fold and arytenoid’s region. The gross appearance of them is that of a well-circumscribed, firm, pink or greyish yellow mass. The mass is solitary, polypoid, sessile, papillary, or cystic. It grows slowly, with patients presenting an average of 7 months after initiation of symptoms. Although some patients may be asymptomatic, common symptoms are hoarseness, cough, dysphagia, odynophagia, otalgia, stridor, and hemoptysis. Most often, the diagnosis is a surprise to the surgeon, made after histological examination of biopsied material from direct laryngoscopy (7, 8, 11). We presented a patient with laryngeal GCT originated from the left arytenoid region which was very rare location, under review of the literature.
