Abstract
Chondrosarcoma of the larynx is a very rare disease, and it is considered to account for less than 1 % of laryngeal malignant tumors. We report two cases that had different clinical courses. Case 1 was a 62-year-old woman who complained of a sensation of having a foreign body in the throat. Direct laryngoscopy revealed a smoothly rimmed tumor in the subglottic area. Incisional biopsy was performed, and the histologic diagnosis was chondrosarcoma (grade II). Case 2 was a 67-year-old man who complained of severe dyspnea requiring tracheotomy. He had been operated on for a posterior-subglottic benign chondroma 12 years ago previously and had not been followed up. Direct laryngoscopy was performed. The recurrent tumor was resected and the histologic diagnosis was chondrosarcoma (grade II). Partial laryngectomy or tumor resection preserving the function of the larynx is considered a curative surgery for low-grade chondrosarcoma. However, we performed total laryngectomy, because they had recurrent nerve palsy and the tumor involved most of the cricoid cartilage.
