Synovial sarcoma of supraclavicular region: A rare case report with review of literature

摘要

Synovial sarcoma is a soft-tissue sarcoma predominantly involving the periarticular regions of the extremities but rare in the head-and-neck region. It is often mistaken for other swellings that are common in the cervical region such as an enlarged lymph node. It is important to recognize this unique entity as synovial sarcoma shows specific genetic and molecular characteristics which helps in the diagnosis, treatment, and prognostication. We present one such rare case in a 29-year-old male with a left supraclavicular region clinically suspected as metastatic lymph node swelling. Histopathology and immunohistochemistry confirmed the diagnosis as poorly differentiated monophasic synovial sarcoma.
