- Abstract
- A previously healthy 54-year-old man complained of progressive voice changes. A firm subglottic polypoid mass was located at the right posterior site, as seen on fiberoptic laryngoscopy, with a distinctly narrowed subglottic space being seen on neck computed tomography, and there were multiple opacities from the cricoid cartilage to the tracheal rings. Resection was done under general anesthesia. The mass-like elevated lesion showed enchondral ossification of the laryngeal cartilage just beneath the squamous metaplastic surface epithelium. The vocal cord mobility was normal. Compared with the computed tomography and the laryngoscopic examination, the polypoid mass-like elevation corresponded to a ossified vocal process of the right arytenoid cartilage. To date, clinically symptomatic ossification of the laryngeal cartilages has presented with foreign body-like impaction. The present case is a rare case of ossification of the laryngeal cartilage that masqueraded as a subglottic polypoid mass. The ossification of laryngeal cartilage is part of the normal aging process, but a tumor-like mass at the airway related with voice changes, like was seen in the present case, is rare. Albeit rare, clinicians and radiologists should be aware that this heterotopic ossification may mimic a polypoid mass-like presentation as well as the accompanying symptoms. (C) 2012 Elsevier Inc.
