Liver Hemangioma : Microscopic Features

Comments:
Microscopic Features: Cavernous hemangiomas of the liver are composed of dilated, anastomosing, thin-walled vascular channels lined by flattened endothelium lacking cytologic atypia or mitotic activity. The channels are supported by thin fibrous septa which often contain mast cells. Normal liver parenchyma is seen at the top left in this image.
