ABSTRACT

Neurofibromatosis is a group of hereditary disorders with autosomal dominant transmission, with a prevalence of 1/3000 births, whose expressivity varies and, frequently, in 50% of cases there is no family history of the disease, which represents the result of a spontaneous mutation. Nerve sheath neoplasms of the larynx are rare and include neurinoma and neurofibroma. These tumors are generally encapsulated and submucosal, with a tendency to localize in the aryepiglottic fold or the ventricular band. This paper reports the case of a 50-year-old male patient with a diagnosis of neurofibromatosis type 1, who started with a 6-month evolution with dysphonia without reaching aphonia, adding 3 months ago dyspnea and foreign body sensation in larynx and laryngeal glomus. Indirect laryngoscopy was performed with a 70^° lens, observing a pedicled lesion dependent on the lateral wall at the level of the epiglottis, smooth-edged which was mobilized with phonation and swallowing. The computed tomography showed a homogenous tumor that did not enhance the contrast medium and was dependent on the lateral wall. Submucosal excision was performed with redundant mucosal resection via endoscopy, with a histopathological report of laryngeal neurofibroma.
