Cutaneous (dicoid) lupus erythematosus is one of the most common immune-mediated skin diseases in dogs. Like other immune-mediated diseases, it is brought on by the abnormal activity of the immune system, whereby it attacks its own body.
Cutaneous lupus erythematosus affects dogs of all ages, with a predisposition in the following breeds: Collies, German shepherds, Siberian huskies, Shetland sheepdogs, Alaskan malamutes, chow chows, and their crosses. It is considered a benign variant of Systemic Lupus Erythematosus (SLE), which is also an immune mediated disease.
Symptoms of cutaneous lupus erythematosus depend on where the immune system is attacking the body, and may appear or disappear and vary in intensity. The following are a few of the more common symptoms seen in dogs:
Lesions associated with this disease may also involve the outer ear area and more rarely, the feet and genitalia.
Although the disease is brought on by abnormal activity of the immune system, the exact cause of the overactivity is unknown. Factors that are suspected to bring on the disease include drug reactions, viruses, and ultraviolet (UV) light exposure.
You will need to give a thorough history of your dog’s health, including the onset and nature of the symptoms, to your veterinarian. He or she will then perform a complete physical examination as well a biochemistry profile, urinalysis, and complete blood count -- the results of which are typically normal. A small tissue sample may also be taken from the affected area for further evaluation.
