We report a case of fibrous pseudotumor of the epididymis as a even more rare location of nodular, fibrous and ossification diffuse proliferation, it may be difficult to distinguish from solid tumors. We also reviewed published report up to date and the differential diagnosis.

Aportamos un caso de pseudotumor fibroso del epidídimo como una localización aún más rara de esta proliferación difusa, nodular y osificada que puede ser difícil de diferenciar de los tumores sólidos. También hemos revisado las publicaciones hasta la fecha así como los posibles diagnósticos diferenciales (AU)

La principal indicación de la PAAF de mama es la existencia de una masa palpable y valorada conjuntamente con la exploración clínica y mamográfica (Triple test); su precisión diagnóstica es de un 99 por ciento. Los criterios citológicos que permiten establecer un diagnóstico de malignidad son: celularidad abundante (celularidad tumoral), grupos celulares tridimensionales y poco cohesivos, pleomorfismo celular, células aisladas con citoplasma, ausencia de núcleos bipolares desnudos y presencia de fondo sucio Aunque la mayoría de los carcinomas mamarios son de tipo ductal, existen parámetros citológicos que, aunque no siempre, permiten identificar subtipos específicos. El material obtenido con la PAAF permite la valoración de factores pronósticos, ya sea realizando técnicas inmunocitoquímicos para receptores hormonales o aplicando criterios que permiten valorar el grado nuclear. La PAAF de mama en las lesiones malignas aporta una sensibilidad del 93 por ciento y una especificidad del 94 por ciento (AU)

We reviewed 98 cases of fine needle aspiration of soft tissue tumors with histologic confirmation performed during an eight-year period and propose a working morphologic classification based on the most prominent cytologic features. Six main tumor groups are recognized: myxoid, round cells, spindle cells, pleomorphic cells, polygonal cells and well differentiated. We believe that this classification allows recognition of the most common soft tissue tumors while helping with the differential diagnosis of other neoplasia, primary or secondary, with similar morphology and a similar presentation.
