Mucoepidermoid Carcinoma of the Larynx: A Case Report.

A case of mucoepidermoid carcinoma of the larynx is reported. A 69-year-old man visited our clinic complaining of hoarsness of approximately 10 months' duration. Laryngeal examination revealed a tumorous mass on the undersurface of the right vocal cord and complete fixation of same-side vocal cord. An excisional biopsy was performed under laryngomicrosurgical techniques. The pathology report diagnosed a mucoepidermoid carcinoma of high grade malignancy. The patient underwent radiotherapy in doses of 30Gy. After radiotherapy, total laryngectomy, right radical neck dissection and left conservative neck dissection were performed. However the patient died 6 months later from distant metastasis.Among malignant tumors of the larynx, mucoepidermoid carcinoma is extremely rare. Only 9 cases of this tumor have been reported in the Japanese literature, and this is the 10th case in Japan. The pertinent literature was also reviewed.
