“…In the chimpanzee, several of the known cases have been secondary to experimental infection with hepatitis B and hepatitis C virus (Porter et al, 2004a). Hepatocellular carcinomas have also been observed in two species of squirrel monkey, S. boliviensis (Borda et al, 1996) and S. sciureus (Morris and Abdi, 1996), cynomolgus macaques (Reindel et al, 2000), an African green monkey (Seibold and Wolf, 1973), and experimentally in rhesus macaques exposed to a variety of carcinogens including nitrosomines and aflatoxin (Adamson, 1989). A hepatoma has been recorded in a sooty mangabey (Clark and Olsen, 1973) and a hepatic neuroendocrine tumor has been reported in a baboon (Aloisio et al, 2009).…”
