| Abstract: | Melanodermas and leukodermas are conditions involving skin pigment changes. Vitiligo, an acquired leukoderma, is an uncommon canine and feline skin disorder, with a likely autoimmune pathogenesis. It is seen more frequently in young adult purebred animals and has no apparent sex predisposition. In Brazil the first report of vitiligo was in 1986. In a 16‐year period, 12 cases of vitiligo, including 11 dogs (six Rottweilers, two Doberman pinschers, one great dane, one boxer, and one mongrel dog) and one cat (Siamese), were diagnosed at our hospital. Diagnosis was based on history, physical examination, Wood´s lamp examination, and histopathologic evaluation (H&E and Masson‐Fontana stains). Among the dogs, seven were male with a mean age of 34.5 months. The clinical evolution was known in five patients. Skin lesions included leukotrichia (100%) and leukoderma of the nose (100%), buccal mucosa (66.5%), lips (85.7%), and footpads (8.5%). Leukonychia was rarely seen. The only lesion in the cat was depigmented footpads. Funding: Self‐funded. |
