Resumen
El sarcoma sinovial es una entidad bien definida clínica y morfológicamente y, a pesar de su nombre, es muy raro en las cavidades articulares. Este sarcoma afecta zonas sin relación aparente con las estructuras sinoviales y representa entre el 5% y el 10% de todos los sarcomas de los tejidos blandos. Se encuentra con mayor frecuencia en las extremidades, especialmente en las inferiores, donde tiende a localizarse en la vecindad de las grandes articulaciones; se han informado muy pocos casos de sarcomas sinoviales en las manos o los pies, con una evolución clínica favorable. Así mismo, es más frecuente de 15 a 40 años de edad (con una edad media de 34 años). Este artículo presenta el caso de una mujer adulta a quien se le realizó el diagnóstico histopatológico e inmunohistoquímico de un sarcoma sinovial en el quinto dedo de la mano derecha.

Abstract
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.
