Biphasic synovial sarcoma of the epiglottis: Case report and literature review

Synovial sarcomas are rare malignant tumors supposed to arise from pluripotent mesenchymal stem cells predominantly affecting the deep soft tissue of the lower and upper extremities in young adults. The occurrence of this tumor entity in the head and neck is very uncommon and hence, timely diagnosis and treatment of synovial sarcoma in this region remain a challenge.We describe the clinical and molecular pathological features of a biphasic synovial sarcoma of the epiglottis, a site where the primary manifestation of this tumor entity has not been documented to date.
