Primary Synovial Sarcoma of the Scalp: An Unusual Presentation
Synovial sarcomas are a rare subset of malignant soft tissue tumors, with an estimated incidence of 2.75 per 100,000 in the general population. Approximately 60% of all synovial sarcomas arise in the lower limbs, more specifically the thigh. On occasion (3-5%), the tumor is found to arise in the head and neck; synovial sarcoma on the scalp is a rare finding. We present a case of primary synovial sarcomaconfirmed by both histology and immunohistochemistry, arising from the scalp in an 18 year old male.
