Hepatocholangioadenoma in a pig.
A Landrace sow had several neoplastic nodules in the liver. Histopathologically, the individual nodules consisted of two types of closely associated neoplastic cells; one was of hepatocellular type, the other of cholangiocellular type. Based on this finding, the term "hepatocholangioadenoma" is considered to be appropriate for this tumour. Previously reported in man, the dog and the duck, a mixed type of primary hepatic neoplasm has now been found in the pig.
