Granular cell-tumor (myoblastoma) of the larynx – report of two cases

Journal Title: Polski Przegląd Otorynolaryngologiczny - Year 2015, Vol 4, Issue 2

Abstract

Myoblastoma is a rare tumor deriving from Schwann cells. It is located mainly in the tongue, skin and subcutaneous tissue, as well as in the bronchi and digestive tract, although it is rarely found in the larynx. It is a benign tumor but recurrence or even malignant transformation is possible. In case of laryngeal location symptoms include hoarseness, cough, discomfort in the larynx or dyspnea. Surgical treatment is necessary through endoscopic or external approach. Authors present two cases of Abrikossoff’s tumor of the larynx. In the first case, tumor was located in the posterior commissure, reaching up to 15 mm in size. Hoarseness was the only symptom. In the second case, tumor was located on the vocal fold near the posterior commissure. Surgery was performed in both cases. In the first case, we used external approach through a laryngofissure, while in the second case surgery was performed endoscopically. Patients have been under follow-up in our Department for several years without relapse.<br/><br/>
