Resumen

El sarcoma indiferenciado (embrionario) del hígado es una neoplasia primaria maligna, que se diagnostica de forma excepcional en el adulto. La ausencia de síntomas específicos, el rápido crecimiento tumoral y la normalidad de los marcadores tumorales hacen de esta neoplasia un proceso de mal pronóstico. Histológicamente, se caracteriza por la presencia de una matriz mesenquimal y un pleomorfismo nuclear. Diversas características histológicas y cromosómicas harían pensar en una posible relación con el hamartoma mesenquimal. El tratamiento de elección es la cirugía, y puede recurrirse a la quimioterapia como tratamiento coadyuvante.

Undifferentiated (embryonal) sarcoma (UES) of the liver is a primary malignant tumor, rarely diagnosed in adults. Because of the absence of specific symptoms, rapid tumor growth, and normality of the common tumor markers, this neoplasm has a poor prognosis. Histologically, UES of the liver is characterized by anaplastic cells within myxoid matrix. Histological, immunohistochemical and chromosomic alterations are similar in UES and in mesenchymal hamartoma, suggesting a relation between these entities. The mainstay of treatment is surgery, while adjuvant treatment could increase survival.
