Laryngeal Chondrosarcoma Arising from the Cricoid Cartilage / 대한이비인후과학회지

ABSTRACT

Laryngeal chondrosarcoma is an uncommon cartilaginous tumor very rarely encountered in the head and neck but most commonly in the sarcoma of the larynx. They occur most often in middle aged and older men. The prognosis of this tumor is potentially poor and surgical resection is generally recommended for the treatment. No benefit of chemotherapy or radiotherapy in chondrosarcoma has been documented in the literature. A 57 year-old male visited our clinic with history of dyspnea and hoarseness. Direct laryngoscopy showed a submucoid, intraluminal mass in subglottic space arising from posterolateral part of the cricoid cartilage. Neck computed tomography revealed a large calcified mass in the larynx. The perioperative frozen section showed it to be grade I chondrosarcoma of the cricoid cartilage. Conservative surgery with complete excision of tumor was performed through laryngofissure approach after tracheostomy. Follow up assesment was performed under close check up at 12 months after the surgery, but we found neither recurrence nor metastasis.
