Abstract
Figure 1. Liver from a striped skunk. An approximately 4.5 3 3.5 3 3 cm, pale yellow, multilocular cystic structure with prominent vasculature protrudes from the surface of the ventrolateral aspect of the left lateral lobe (long arrows). In the same lobe, there is an approximately 1.5-cm darker cyst present in the ventromedial aspect (short arrows). A much smaller cyst is seen in the right lateral lobe as well (arrowheads). Biliary cystadenoma is a benign cystic tumor derived mainly from the intrahepatic bile ducts and less frequently from the extrahepatic bile ducts and gallbladder.5 The neoplasm is rare and has been reported in cats, dogs, pigs, sheep, rats, and humans.1,3–11 Among animals, it is most often encountered in old cats and dogs.1,7 It can be single or multiple with 1 or more hepatic lobes involved.1 Although this neoplasm could cause persistent upper abdominal pain in human patients,6 its clinical significance in animals is not known because it is usually an incidental finding at necropsy.1,7 No reports of biliary cystadenoma in exotic animals have, to our knowledge, been published. This report describes the morphologic and immunohistochemical characteristics of a biliary cystadenoma from a striped skunk (Mephitis mephitis).
