A clinicopathologic study on SS18 fusion positive head and neck synovial sarcomas

Sarcomas of the head and neck are rare, accounting for only 1 % of all head and neck malignancies [1]. Synovial sarcomas (SS) comprise about 10% of all soft tissue sarcomas, with SS of the head and neck (SS-HN) representing less than 0.1% of all head and neck cancers [1,2]. SS represents less than 10% of all head and neck sarcomas and the head and neck region accounts for less than 10% of all cases of SS [1]. The lower limb accounts for majority of SS cases [3], while the most common head and neck site for SS is the parapharyngeal neck region [4,5].
