Laryngeal myxoid neurofibroma misdiagnosed as myxoma: a case report

Neurogenic tumours constitute a very small percentage of all neoplastic lesions of the head and neck region. Neurogenic tumors of the larynx are extremely rare. Two types of neurogenic tumors must be distinguished: Schwannomas and neurofibromas. Neurofibromas arise from the sheath of nerve fibers and are characterized by prominent collagen production and trapped nerve fibers. In the larynx, the most common sites of origin are arytenoids and aryepiglottic folds. Because of benign nature of this tumor, conservative surgery is recommended as the management of choice. Only few cases of laryngeal myxoid neurofibroma have been reported in literature and this article presents one case of laryngeal myxoid neurofibroma, which at first was misdiagnosed as myxoma, with brief review of literatures.
