Types

- capillary hemangioma
- cavernous hemangioma

Differential diagnosis

- hemangiomatosis
- hereditary hemorrhagic telangiectasia (HHT): aberrant portal vessels, dilated vascular channels within portal tracts
- infantile hemangioendothelioma: atypia present, although not necessarily everywhere
- peliosis hepatis / hepatic peliosis : no fibrous septa
