Monophasic Synovial Sarcoma of the Infratemporal Fossa—Case Report and Review of the Literature

Abstract

Synovial sarcoma (SS) represents about 10% of all soft tissue sarcomas. It is believed that its origin would be found in cells that are related neither to ultrastructural nor to histological features of the synovial tissue. Head and neck is very rarely affected, with the lower extremities being most frequent. Complete resection with or without radiotherapy and chemotherapy is currently considered the best available therapy. This time we present the case of a patient with SS located in the infratemporal fossa, its diagnosis, treatment and evolution. According to our knowledge it is the first reported case in South America.
