BACKGROUND: Generalized discoid lupus erythematosus (DLE) is an autoimmune skin disease variant rarely reported in dogs. The antimalarial immunomodulator hydroxychloroquine has been suggested as maintenance therapy for generalized DLE in one dog, but several recurrences were noted in the 1 year follow-up of that patient.
HYPOTHESIS/OBJECTIVE: To describe the effective treatment of generalized DLE with ciclosporin in one dog.
ANIMAL: A 6-year-old, castrated male crossbred dog was presented with pruritic, well-demarcated annular to polycyclic, hyperpigmented plaques with marginal erythema on the dorsal head, neck, trunk and medial extremities; these had been nonresponsive to treatment with doxycycline and niacinamide.
METHODS: Investigation included complete blood count, serum chemistry profile, urinalysis, serum antinuclear antibody test, histopathological examination and direct immunofluorescence testing of skin biopsies.
RESULTS: The presence of lymphocyte-rich interface dermatitis on histology, together with generalized chronic recurrent hyperpigmented plaques, was consistent with the diagnosis of a generalized variant of DLE. The absence of systemic signs and unremarkable laboratory tests excluded concurrent systemic lupus erythematosus. Treatment was initiated with oral dexamethasone and ciclosporin. After 1 month, dexamethasone was discontinued and oral ketoconazole was added to the therapeutic regimen. Four months later, pruritus and erythema resolved, with most skin lesions becoming impalpable. Over the last 6 months, the patient's DLE was maintained in remission with oral ciclosporin and ketoconazole in combination every 3 days.
CONCLUSIONS AND CLINICAL IMPORTANCE: The combination of ciclosporin and ketoconazole appeared effective to induce and maintain lesion remission in this dog with generalized DLE.
