Glottic Neurofibroma: An Unusual Case Report

Solitary neurofibromas of the larynx occur sporadically and usually tend to involve the aryepiglottic folds. Non-plexiform variants of neurofibromas involving the glottis are extremely rare and may have defined margins versus plexiform subtype which are often unencapsulated and associated with Von Recklinghausen’s disease. We report an unusual case of isolated glottic neurofibroma in an elderly male with gradually progressive hoarseness of voice with stroboscopy findings of a right unilateral, bulky subepithelial lesion mimicking a vocal fold cyst. He underwent laser-assisted trans-oral microlaryngeal surgery and excision of lesion in-toto by micro-flap technique following which histopathological examination reported a neurofibromatous lesion. On performing immunohistochemistry the S-100 protein was positive which confirmed the diagnosis. The patient has been recommended regular follow-up to watch for recurrence.
