Carcinomas and other lesions of the liver in mice ingesting organochlorine pesticides.

Carcinomas of the liver were readily induced in male and female mice given organochlorine pesticides orally. The carcinomas were predominantly hepatocellular, with a few being cholangiocellular, and varied from well differentiated to poorly differentiated to undifferentiated. They are capable of invading, metastasizing, and killing the mice. Hemangiosarcomas, leimyosarcomas, and reticulum cell sarcomas were also occasionally seen in mice receiving these chemicals. Hepatic vein thrombosis and hepatic necrosis was observed in some mice.
