Sarcoma sinovial digital Digital Synovial Sarcoma

Synovial sarcoma is a clinically and morphologically well defined entity which, in spite of its name, is rare in joint cavities. This sarcoma affects zones without any apparent relation to synovial structures and represents from 5% to 10% of all sarcomas in soft tissues. It is most frequently found in the extremities, especially the lower ones, where it tends to be located in the vicinity of the major articulations; there are very few favorable reports on the clinical evolution of synovial sarcomas in the hands or feet. It is most frequent between the ages of 15 to 40 (median age, 34). This article presents the case of an adult woman who underwent histopathologic and immunohistochemical diagnosis of a synovial sarcoma on the little finger of her right hand.
