Oncocytic lesions of the larynx

True laryngeal adenomas are considered extremely rare and some doubt their existence. Laryngeal lesions having oncocytes as the predominant cell type have been described in the literature under a variety of different names: oncocytoma, oncocytic papillary cystadenoma, papillary cystade‐noma, oxyphilic granular cells adenoma, etc. The oncocytes originate from changes in normal acinic and ductal cells. The significance of these changes is controversial. Whether the oncocytic laryngeal lesions represent true neoplasms or are degenerative in nature remains to be determined.
