The exact [[pathogenesis]] of [[hepatocellular adenoma]] is still unknown, however, its [[Association (statistics)|association]] with [[Oral contraceptive|oral contraceptive use]] is well established.

The [[hepatocellular adenoma]] have been linked to [[Mutation|mutations]] in [[HNF1A|HNF1a]] and [[Beta-catenin|beta catenin]] [[Gene|genes]]. On [[gross pathology]] it appears as a [[solitary]] or multiple, unencapsulated and well demarcated [[mass]], which can occasionally be [[pedunculated]] or encapsulated and also form multiple [[Mass|masses]]. The [[Tumoral|intratumoral]] [[hemorrhage]] can give rise to soft, [[Necrosis|necrotic]], red brown lesion on gross appearance.

Overview

The exact pathogenesis of hepatocellular adenoma is still unknown, however, its association with oral contraceptive use is well established. It has also been associated with long term use of anabolic androgenic steroids and glycogen storage diseases. The hepatocellular adenoma have been linked to mutations in HNF1a and beta catenin genes. On gross pathology it appears as a solitary or multiple, unencapsulated and well demarcated mass, which can occasionally be pedunculated or encapsulated and also form multiple masses. The intratumoral hemorrhage can give rise to soft, necrotic, red brown lesion on gross appearance. The microscopic features of hepatocellular adenoma include benign hepatocytes arranged in mildly thickened cell plates, with a preserved reticulin network and thin walled arteries. The arteries and arterioles are not accompanied by other portal tract elements such as bile ducts, portal veins or fibroconnective tissue.
