In two hybrid breed pig carcasses a marked jaundice and splenomegaly were observed. Macroscopically the liver showed no alterations.

Histopathological examination of the liver and spleen samples revealed that the liver had no significant lesions, spleen changes were due to extensive hemorrhagic areas. Inflammatory-necrotic lesions were ruled out.

The cause of these hemorrhages is unknown, but very likely due to splenic torsion or trauma. The cause of jaundice and if it is related to the splenic torsion is uncertain. One possibility is that the degradation of extravasated erythrocytes caused the jaundice, it would then be a prehepatic jaundice due to hemolysis.

Enlarged spleen (50 cm x 20 cm) with discoloration on the surface. The liver was normal.
