Laryngeal chondroma: a benign process with long-term clinical implications.

Chondroma of the laryngeal cartilage is a rare, benign neoplasm which can manifest as a neck mass or, if situated within the airway, as slowly progressive obstruction, hoarseness or dyspnea. The most common location for chondroma is the posterior lamina of the cricoid cartilage; the next most common locations are the thyroid, arytenoid and epiglottic cartilages. Chondroma and low-grade chondrosarcoma are difficult to distinguish from one another histologically. Although chondrosarcoma reportedly recurs, local surgical excision without radical margins and with long-term clinical follow-up is recommended. We report one case of thyroid cartilage chondroma and include a review of radiologic studies and histopathologic analysis results. We also report a second case with severe airway obstruction caused by a large cricoid chondroma. A review of the English language biomedical literature on laryngeal chondroma is included.
