Canine Discoid Lupus Erythematosus is an uncommon autoimmune disease of the skin. The most common symptoms are scaling and loss of pigment on the nose. There are two forms of Discoid Lupus Erythematosus: systemic lupus erythematosus (SLE), that can affect multiple systems within the body, and a milder form that is limited to the skin, discoid (or cutaneous) lupus erythematosus (DLE).
Avoiding exposure to the sun and using sunscreens (not containing zinc oxide) will alleviate symptoms. Topical medications and treatments may also be necessary to improve dryness and other irritating symptoms.
