Hemangiomas are the most common benign liver tumours (1-5% incidence). Most are found incidentally at autopsy, laparotomy, or on imaging. They are usually small, but rarely become very large.
Grossly, they appear dark red and spongy. Microscopically, they are composed of large vascular spaces. Large tumours may present with pain due to thrombosis or rarely rupture. Only hemangiomas with severe symptoms are resected.
