(A) Liver biopsy showing sinusoidal infiltration by pleomorphic spindle cells typical of hepatic angiosarcoma. There is disruption of the normal trabecular architecture with hepatocyes forming glandular structures containing bile plugs ("cholestatic rosettes"). (B) Spindle cells are strongly immunoreactive for the vascular endothelial marker CD34. (A = Haematoxylin and eosin, B = immunoperoxidase).
