Antibiotic responsive ulcerative dermatoses in German Shepherd Dogs with mucocutaneous pyoderma.

Abstract

Mucocutaneous pyoderma is a disease of unknown aetiology affecting mucocutaneous skin and is responsive to antibacterial therapy. It is reported to affect the lips, nasal planum, nares, perioral skin and less commonly, the eyelids, vulva, prepuce and anus. Three cases of mucocutaneous pyoderma are presented. Two of the cases showed ulcerative lesions in the inguinal and axillary regions in addition to more typically reported lesions. Two of the dogs had concurrent atopic dermatitis and the third had clinical signs suggestive of hyper-sensitivity disease. The clinical and histopathological features, differentiation of mucocutaneous pyoderma from discoid lupus erythematosus, and long-term management of mucocutaneous pyoderma are discussed.
