Granularzelltumor des Larynx

Abstract

Granular cell tumors are benign subcutaneous or submucosal lesions of neurogenic origin. They are quite commonly found in the head and neck region, particularly in the tongue. However, only about 200 cases of laryngeal granular cell tumors have been reported so far. Most laryngeal granular cell tumors are located in the posterior part of the vocal fold and in the posterior commissure. Differentiation from inflammatory as well as from malignant lesions is possible only by biopsy. The treatment of choice is complete excision. However, tumor extension and expected morbidity of the surgery will inevitably influence the extent of the resection. Recurrences after complete excision are rare.
