Successful treatment of a mucous membrane pemphigoid in a young dog.

Abstract

Mucous membrane pemphigoid was diagnosed in a 2.5-year-old male intact foxhound-beagle cross which was presented with an acute onset of non-pruritic, multifocal, slowly progressive erosive-ulcerative dermatitis predominantly affecting the nasal planum, eyelids and muzzle with multiple vesicles on the inner pinnae, oral mucosa and tongue. The diagnosis was based on clinical signs and histological examination of skin biopsies. The patient did not respond to immunosuppressive prednisolone therapy, but went into complete remission with oral doxycycline and niacinamide and stayed in remission on long-term exclusive niacinamide treatment.
