Focal Nodular Hyperplasia

Solitary or multiple benign hepatic vascular tumors, usually occurring in women of 20-50 years of age. The nodule, poorly encapsulated, consists of a central stellate fibrous scar and normal liver elements such as HEPATOCYTES, small BILE DUCTS, and KUPFFER CELLS among the intervening fibrous septa. The pale colored central scar represents large blood vessels with hyperplastic fibromuscular layer and narrowing lumen.
