Laryngeal chondrosarcoma is a rare tumor, accounting for 0.2% of all malignant laryngeal tumors. Since grade 1 laryngeal chondrosarcoma is associated with a good prognosis, larynx-preserving surgery is desirable. This report describes a case of cricoid chondrosarcoma in which a cricoid cartilage defect was reconstructed with muscle-pedicled thyroid cartilage after tumor resection. A 62-year old man was referred to our hospital due to a subglottal tumor that was incidentally detected on cervical spine MRI. CT images revealed a tumor that had developed from the cricoid cartilage, and the diagnosis of chondrosarcoma, grade 1 was confirmed based on the findings of a histological examination. The patient underwent partial cricoidectomy with reconstruction using muscle-pedicled thyroid cartilage. Although tracheostomy was performed intraoperatively, he was decannulated 2 months later. At 1 year after surgery, the patient is currently alive with no evidence of recurrence and normal oral feeding.
