Abstract

Hibernomas are tan to dark brown with areas of gray to yellow where necrotic. The neoplasm is lobulated, giving a bosselated appearance to the surface (Fig.171). In the rat the neoplasm may reach 40 mm in each dimension. The cut surface (Fig.172) varies in color (as does the outside surface), may have areas of hemorrhage, and is somewhat greasy in texture. The neoplasm will float in formalin fixative similar to a lipoma. Lipid from the tumor may be seen on the surface of the fixative.

Synonyms
