Primary @entity409 is rare. Here we report an unusual case of @entity409 containing combined hepatocellular @entity201 . A mass in the right liver lobe of a 45-year-old @entity1 was accidentally discovered by ultrasonic inspection and computed tomography (CT) scan. Surgical resection was performed following a diagnosis of primary @entity96 . @entity3909 and @entity3038 were present, and diagnosis of @entity409 was confirmed. The @entity3909 element consisted of hepatocellular @entity189 and foci of @entity201 . The @entity3038 element was composed of spindle cells and bizarre cells, as well as foci of @entity421 and @entity511 . @entity157 cells diffusely expressed both hepatocyte specific markers cytokeratin (CK) 8/18 and cholangiocyte specific markers @entity4166 , and @entity242 cells were positive for @entity2277 . Interestingly, both @entity3909 and @entity3038 cells expressed epithelial membrane antigen. CD117-positive ductular reactions and small undifferentiated cells were observed. A liver progenitor cell origin of the @entity409 was proposed.
