Hepatocytes are known for their round nuclei.|280x280px]]A haemangioma is a benign tumor of the vessels, originating from endothelial cells. They can be found in the skin, nasal cavity and parenchymal organs, especially the liver. Haemangiomas contain many small cavities called caverna, which are lined by endothelium and can be filled with blood. Rupture of haemangiomas, with resulting haemorrhage, is the most important clinical consequence of this type of tumor.[[File:Cavernous haemangioma of the liver overview.png|thumb|Overview of the slide|280x280px|left]][[File:Cavernous haemangioma of the liver filled caverna.png|thumb|Caverna with blood|281x281px]]
