FIRST PARAGRAPH: Synovial sarcoma (SS) is a unique tumor that usually involves the large joints. Approximately 10% of these tumors develop in the neck, oropharynx, hypopharynx, and larynx. Despite the name, these tumors neither originate from synovium nor express synovial differentiation. SS typically presents in young adults (median age: 25 yr). The male-to-female ratio is 3:1. Symptoms are site-specific but tend to be nonspecific. SS typically appears as a solitary, painless mass, occasionally accompanied by dyspnea or hoarseness. The diameter of the lesion ranges from 1 to 12 cm. The cut surface is yellow, firm, whorled, gritty, and friable; cyst formation with hemorrhage or mucoid material is often seen.
