ABSTRACT
Presentamos un nuevo caso de fibrohistiocitoma maligno primario de pulmón y revisamos la literatura con la intención de exponer sus principales características clínicopatológicas. Se trata de una entidad poco frecuente, cuya etiopatogenia sigue siendo desconocida. Es una lesión de difícil diagnóstico, que plantea el diagnóstico diferencial con sarcomas metastásicos y con lesiones fusocelulares primitivas, fundamentalmente el carcinosarcoma, el carcinoma fusocelular y, en niños, el pseudotumor inflamatorio. Es imprescindible un estudio clínico radiológico que descarte otra lesión primitiva y la ayuda de técnicas de inmunohistoquímica y mícroscopia electrónica (AU)
