A Case of Synovial Sarcoma Arising in the Hypopharynx

Synovial sarcomas are rarely occurring, highly malignant tumors of mesenchymal origin. Most cases are confined to the extremities. Fewer than 100 cases of synovial sarcoma have been reported in the head and neck area. We experienced a 24-year-old male patient who first complained of globus sensation. Initial suspension laryngoscopic biopsy specimen of the primary lesion was consistent with hypopharyngeal synovial sarcoma. Surgical excision through lateral pharyngotomy approach and postoperative radiotherapy were performed. We report this rare case with a literature review. (Korean J Otolaryngol 40：9, 1997
