Abstract

Reports of neoplastic diseases in the Siberian chipmunk (Eutamias sibiricus) are limited. The authors describe herein two necropsy cases of Siberian chipmunks with squamous cell carcinoma; both of which showed self-biting behaviors on presentation to the clinician. In both cases, the neoplasms comprised trabeculae and islands of polyhedral cells, supported by moderate amounts of fibrous stroma. Anisocytosis and anisokaryosis were moderate to prominent. Neoplastic cells were occasionally keratinized, with a keratin pearl formation. In one case, valvular endocardiosis of the left and right atrioventricular valves with secondary pulmonary and hepatic lesions was incidentally diagnosed. This report provides the first documentation of squamous cell carcinoma and endocardiosis in the Siberian chipmunk.
