Synovial sarcoma is a malignant tumor of soft tissue that is rarely found in the head and neck. Even less common are metastasis within the head and neck.We describe a case of a delayed metastatic synovial sarcoma to the scalp. A man who had been diagnosed and treated 16 years previously for monophasic synovial sarcoma of the groin, presented with a new scalp lesion confirmed to be metastatic monophasic synovial sarcoma. Wide local excision and sentinel lymph node biopsy (SLNB) were performed and adjuvant radiation therapy was deferred.A positron emission tomography (PET)/CT was obtained 3 months after surgery and showed no evidence of local recurrence or metastatic disease.This case report describes a rare case of synovial sarcoma metastasizing to the scalp. The genetic, histopathologic, and clinical features of synovial sarcoma are reviewed with a focus on their manifestation and management within the head and neck.
