Oncocytic papillary cystadenomatosis of the larynx.

Symptomatic oncocytic disease of the larynx is rare. Review of the world literature reveals that isolated, symptomatic cases of oncocytoma of the larynx have been previously reported to involve discrete sites usually the laryngeal ventricles and vestibular folds. A unique case of multifocal cystic oncocytic hyperplasia necessitating laryngectomy is reported. CT scan of the larynx suggested destruction of the cartilage. Malignant histological features were not present. This report raises the question whether previously described cases of oncocytoma of the larynx also had diffuse involvement. If oncocytosis is a diffuse process then it is suggested that patients should be kept under review for recurring lesions.
