A case of pyoderma gangrenosum in a dog successfully treated with prednisolone alone Een geval van pyoderma gangrenosum bij een hond succesvol behandeld met enkel prednisolone

In this case report, a markedly painful ulcerative dermatitis consistent with pyoderma granulosum is reported in a 2.5-year-old entire female Maltese dog. The dog had a nasal stridor and irregular ulcers with raised inflammatory borders involving the lumbar area, tail and the hindlimbs. The lesions did not respond to antibiotics. Histopathologic features include deep crateriform ulcerations with massive infiltrations of neutrophils beneath and adjacent to the ulcers. Treatment with prednisolone (Kela Laboratories, Sint-Niklaas, Belgium) alone resulted in the resolution of nasal signs and all skin lesions.
