'''Hepatocellular adenoma''', also '''hepatic adenoma''', or rarely '''hepadenoma''', is an uncommon benign [[liver]] tumour which is associated with the use of types of [[hormonal contraception]] with a high [[Estrogen|estrogen]] content.<ref>{{cite journal | author = Rooks J, Ory H, Ishak K, Strauss L, Greenspan J, Hill A, Tyler C | title = Epidemiology of hepatocellular adenoma.

==[[Hepatocellular adenoma screening|Screening]]==


*Color Doppler US may demonstrate peripheral peritumoral vessels and intratumoral vessels that typically have a flat continuous or, less commonly, triphasic waveform.  *These Doppler US features are reported to be absent in the vessels within focal nodular hyperplasia and may be useful in distinguishing the two disease entities.  *Nevertheless, most adenomas are not specifically diagnosed at US and are usually further evaluated with CT or other imaging modalities.

All hepatocellular adenoma should be surgically resected, because of the risk of rupture causing bleeding and because they may contain malignant foci.<ref>{{cite journal | author = Toso C, Majno P, Andres A, Rubbia-Brandt L, Berney T, Buhler L, Morel P, Mentha G | title = Management of hepatocellular adenoma: solitary-uncomplicated, multiple and ruptured tumors. | journal = World J Gastroenterol | volume = 11 | issue = 36 | pages = 5691-5 | year = 2005 | id = PMID 16237767}}''[http://www.wjgnet.com/1007-9327/11/5691.asp Full text]''</ref>
