The nodular form, which includes approximately two-thirds of all examples, is characterized by multiple nodules which tend to remain discrete but not rarely blend into the surrounding liver substance.

The cells are arranged to form bile canaliculi, which may be dilated with inspissated bile since they do not join secretory ducts. Like normal liver cells, the tumor cells are large, often larger than normal, with the cytoplasm eosinophilic and granular while the cell borders are distinct and may be flattened and angulated (HERXHEIMER, 1930). The nuclei also are large and round with prominent nuclear membranes. Some are pale, with the chromatin arranged in various-sized granules. Other nuclei are hyperchromatic.
