Capybara is a large mammal rodent that inhabits the Argentinean territory. The species is an important source of animal protein and its skin is an important by-product which can be considered as an economic resource for sustainable utilization, as evidenced by the numerous studies on the capybara regarding parasitical diseases, characteristics of the skin and morphology of the digestive tract, and others. However, no studies that characterize the morphology of the liver have been found. Anatomically, the liver of capybara is thick and similar to that of carnivores, having five lobes overlapping each other. It presents lobular architecture and portal tracts consisting of vascular structures and bile canaliculi. Liver lobules do not exhibit the characteristic polygonal shape and their boundaries are poorly defined. Liver cells are irregularly polyhedral, variable in size, being the cytoplasm eosinophil, with a rounded, central, basophilic nucleus with dispersed chromatin and evident nucleolus. Histological organization of the organ keeps similarity with the descriptions of that of domestic mammals and experimental rodents.
