An atypical case of pyoderma gangrenosum in a dog

Abstract

Neutrophilic and ulcerative dermatitis is reported in a mixed breed dog. The condition was considered to be an atypical case of pyoderma gangrenosum. Clinically, it had a more superficial ulceration, a more pronounced pustular component and lacked the characteristic cutaneous pain and tenderness of the lesions. The diagnosis of pyoderma gangrenosum was made as a diagnosis of exclusion. The dog showed an excellent response to treatment with ciclosporin (Cyclavance, Virbac, Leuven, Belgium).
