In 1999, Nguyen et al divided focal nodular hyperplasia (FNH) in 2 groups, the classical and nonclassical. The former also included those cases of FNH with classical characteristics exhibited "on a subtle scale," whereas the latter included among others mainly the telangiectatic FNH (T-FNH) variant. Hepatocellular adenoma (HCA) was classically ...
