Oncobytic papillary cystadenomatosis of the larynx: a clinicopathologic entity.
A patient with numerous oncocytic lesions of the larynx is reported. Laryngectomy for a concurrent epidermoid carcinoma made it possible to study the entire laryngeal mucosa. A hyperplastic component to the oncocytic metaplasia of the ductal epithelium of the seromucinous glands resulted in a spectrum of lesions varying from simple oncocytic cysts to solid lesions that may be erroneously interpreted as true neoplasms (oncocytomas). Oncocytic papillary cystadenomatosis is a condition affecting the larynx in a diffuse fashion suggesting the need for follow-up on patients with biopsy proven oncocytic lesions.
