Abstract
Hepatocellular carcinomas are usually visible grossly and range in size from several millimeters to several centimeters (Farber 1976; Greenblatt and Lijinsky 1972; Goodman et al. 1994; Fig. 34). They are roughly spherical, although multilo-bulation may distort the shape (Fig. 35), and appear as single or multiple, light-tan to dark-red lesions in the liver. Rats chronically exposed to potent hepatocarcinogens frequently have multiple hepatocellular carcinomas alone or in combination with hepatocellular adenomas (Fig. 34). The liver of such an animal may be almost totally replaced by numerous, variably sized neoplastic and preneoplastic lesions.
