A Case of Synovial Sarcoma Arising in the Supraglottis / 대한이비인후과학회지

ABSTRACT

Synovial sarcoma is a rare tumor that usually occur in the extremities of young adults. The head and neck is relatively a rare location as fewer than 100 cases of synovial sarcoma have been reported in the head and neck area. In the head and neck region, however, the most common site is the hypopharynx. There are 12 cases with laryngeal localization in the literature. We experienced a 30-year-old female patient with an endolaryngeal mass. Initial suspension laryngoscopic biopsy specimen of the primary lesion was consistent with laryngeal synovial sarcoma. The tumor arose from the right false vocal cord. It was treated by extended vertical hemilaryngectomy and postoperative radiotherapy. Microscopically, the tumor was characterized by a monophasic fibrous appearance. We report this rare case with a literature review.
