Bilateral laryngeal pseudoparalysis in xanthoma disseminatum treated by endoscopic laser medial arytenoidectomy.

Abstract

Xanthoma disseminatum is a rare non-Langerhans' cell histiocytosis, characterized by papular cutaneous eruption, possible mucosal involvement, and frequent association with vasopressin-sensitive diabetes insipidus. Herein we report a case of xanthoma disseminatum with pharyngolaryngeal involvement. In this patient, mucosal xanthomas involving the arytenoid cartilages and the interarytenoid area resulted in laryngeal stenosis and severe impairment of both cricoarytenoid joints' motility. Endoscopic CO2 laser medial arytenoidectomy, according to the technique described by Crumley (1993), and vaporization of interarytenoid xanthomas were successfully performed, thus reestablishing bilateral cordal motility and the laryngeal airway. Four years later, a CO2 laser revision was necessary because of recurrence of xanthomas in the posterior larynx. Two years after the latter operation, the patient has no signs of laryngeal obstruction and has a normal voice quality. This case report suggests that endoscopic medial arytenoidectomy may be successfully used in the treatment of bilateral laryngeal pseudoparalysis secondary to xanthoma disseminatum.
