Intrinsic malignant schwannoma of the larynx. A case report.

The first case of an intrinsic laryngeal malignant schwannoma is reported. The diagnosis of a malignant schwannoma is difficult to establish without gross evidence of its origination in a nerve. Although surgery remains the mainstay of treatment, a combination of surgery and radiotherapy appears promising. The prognosis in most cases is poor, with death usually resulting from persistent or locally recurrent disease.
