The discoid lupus erythematosus is a canine autoimmune disease that presents clinically in the form of erythema, depigmentation, scaling, erosions/ulcers and scars on the nasal plane and proximal dorsal region of muzzle. A six-year-old Siberian Husky with a history of pruritus, erythema, ulceration and depigmentation in the nasal region was served at a veterinary service specializing in dermatology. A complete blood count and serum biochemistry, serology for canine leishmaniasis, imaging tests (chest x-ray and abdominal ultrasound), and histopathology were requested. Hematobiochemical tests showed results within normal standards for specie, and serological test for canine leishmaniasis was considered negative. The imaging tests did not accused any changes in canine specie. The histopathological examination revealed the presence of interface dermatitis, irregularly thickened epidermis and inflammatory infiltration at dermo-epidermal junction and interstitial edema. Laboratory and imaging findings together with histopathological results contributed to the diagnostic definition of discoid lupus erythematosus, an autoimmune skin disease rarely present in the routine of small animal veterinary clinics. The results obtained in the study highlight the importance of identifying discoid lupus erythematosus in dogs to ensure correct treatment.
