Peliod hepatocellular carcinoma in a domesticated ferret (Mustela putorius furo).

Peliod hepatocellular carcinoma was diagnosed in a domesticated ferret (Mustela putorius furo). The diagnosis was made using immunohistochemical analysis, histologic examination, and the accepted classification schemes based on histomorphologic features. Bilateral, adrenocortical hyperplasia also was evident. Speculation about a possible association between the variant of hepatocellular neoplasia diagnosed in this animal and its adrenal pathologic changes was done.
