Abstract

<p>Chondrosarcoma of the larynx is a rare disease accounting for less than 1% of all laryngeal malignancies. We report a case of chondrosarcoma in a 50-year-old male who presented with a one-year history of dyspnea originally diagnosed as asthma. Immediate histopathological examination revealed chondrosarcoma. A total laryngectomy was performed on this advanced malignancy with severe destruction of the cricoid cartilage. Histopathology of the excised tumor revealed binucleation, hyperchromasia, nuclear atypia, and hypercellularity, with indication of the coexistence of grade I and grade II chondrosarcoma. No evidence of recurrence has been observed during 6 years since surgery.</p>
