_Adenoma_ has been met with by McFadyean, Johne, Kitt and Bollinger.
They hung as pediculated tumors from the surface of the liver, and were
in part wedged into its substance displacing the hepatic tissue and
vessels. In general they consisted of a dense fibrous stroma with
cylindroid and biliary cells in great abundance, sometimes arranged in
tubular form. Specimens described by Kitt and Bollinger attained to the
size of a man’s head and were stained of a deep green color.
_Carcinoma._ Casper reports a case of hepatic cancer in the sheep
secondary to cancer of the mesentery.
