From a young Golden Retriever with a history of weight loss and ascites for 3 months. This is a micronodular cirrhosis. The parenchyma is divided into variable sized small nodules of regenerating hepatocytes by thin fibrous septa. The entire liver must be involved. Note Abnormal vascular relationships.
Many smaller nodules contain neither portal tracts nor central veins.
There are numerous abnormal thin-walled vessels in the fibrous septa. Fatty change in many of the regenerating hepatocytes. Macroscopically, the regenerating nodules were cream coloured and resembled small tumour deposits. . . .
