Biphasic Synovial Sarcoma of the Pyriform Fossa: Case Report

Arsheed Hussain Hakeem*, Hassaan Javaid, Meenakshi Swain, Novfa Iftikhar

Synovial sarcomas are rare malignant tumours originating from pluripotent mesenchymal stem cells. These sarcomas are usually seen in the deep soft tissue of the lower and upper extremities, particularly in adolescents. Head and neck is a rare site for these sarcoma and pyriform sinus is more unusual site to occur. We report a biphasic synovial sarcoma of the left pyriform sinus in a 16-year-old male and describe its clinical, pathological and immunohistopathology features. With this background the existing literature is being reviewed. The standard of care is wide surgical excision with adjuvant radiation therapy to increase local control and prolong disease-free survival.
