Synovial sarcoma of the para pharyngeal space: a case report and literature review

Abstract

Synovial sarcoma (SS) is a malignant neoplasm that arises from primitive pluripotential mesenchymal cells . It is a high-grade histological variety of sarcoma and it accounts for 7-10% of all soft tissue sarcomas. Head and neck locations represent only 0.7% to 10% of all cases. Primary parapharyngeal synovial sarcoma (PPSS) is rare representing only 0.5% of all tumors of the head and neck region. We describe through a clinical case the clinical, radiological and histological features of PPSS and we discuss its therapeutic management.
