A 1-year-old, spayed female, Schnauzer mixed breed dog began developing lesions at 5 months of age. The dog had been previously diagnosed with a fungal infection and started on an antifungal medication. The lesions progressed. The dog was seen on referral with suspected ischemic changes given the distribution of lesions on the face and distal limbs. Treatment was begun with cyclosporine, but the lesions continued to progress after 3 months. No mites, bacteria, or dermatophytes were detected on routine diagnostics. The lesions were diffuse and mostly symmetric. The skin was smooth, but adherent scale was noted. Most recently, hyperpigmented plaques had formed over the dorsal aspect of the head. Figure 1.
