Erythema multiforme in a ferret (Mustela putorius furo).

Erythema multiforme, an uncommon skin disease resulting from an aberrant immune response, was diagnosed in a domestic ferret (Mustela putorius furo) based on clinical signs and skin biopsies, and this seems to be the first case report of this dermal disease in the ferret. This article discusses treatment and response, and reviews the small animal literature as it relates to disease pathophysiology and treatment.
