Exfoliative cutaneous lupus erythematosus (ECLE) is a rare, inherited skin disease. It is a severe, widespread form of cutaneous lupus, and it is seen mostly in young German Shorthaired Pointers [1][2]. Exfoliative means the skin sheds in scales.

If your German Shorthaired Pointer has scaling or crusting skin, see your vet. Other skin diseases can look the same.

What you may notice

Signs usually appear in a young dog. In published reports the typical age at onset was around 8 months, though it ranged from a few weeks old to over 3 years [1].

Scaling is the first sign in nearly every case, often with hair loss. Scales may stick to the hairs and bind them into clumps [1][2]. Changes tend to begin on the face (muzzle, forehead and ear flaps) and along the back, then spread to the belly, chest and legs. In time the skin can develop sores and crusts [1].

Some dogs are itchy [1].

Signs beyond the skin

ECLE often affects the whole body, not just the skin [1]. Your dog may:

  • have swollen lymph nodes (small glands that swell when the body fights disease) [1];
  • run a fever that comes and goes [1];
  • have sore joints, which can show as stiffness, a shifting limp, a hunched back or not wanting to move [1][2].

Blood tests may show anaemia or low platelets [1][2]. Fertility problems have also been reported [1]. In a small study, affected dogs developed a kidney disease that leaks protein into the urine, so the researchers advise checking kidney function in these dogs [4].

How vets diagnose it

Your vet looks at the dog’s breed, age, history and skin signs, and takes skin biopsies (small pieces of skin sent to a lab) [1]. A biopsy is the main test that shows the typical changes [1].

Other diseases that cause scaling and crusting, such as sebaceous adenitis and pemphigus, need to be ruled out. Those usually start in older dogs [1]. For lupus and pemphigus on the nose, see dry, crusty nose in dogs.

Which dogs get it

ECLE is passed on as a recessive trait: a dog gets the disease only if it inherits the faulty gene from both parents [1][3]. The gene change has been found in German Shorthaired Pointers and in a Vizsla, a closely related breed [1][3]. Knowing the change makes genetic testing of breeding dogs possible [3]. Ask your vet about testing.

Treatment

Your vet will advise on care for your dog. Treatment aims to calm the immune system, but the response is often poor [1][2].

At home, as directed by a vet:

  • do not put human or leftover medicines or skin products on your dog unless your vet says so;
  • tell your vet about any change in your dog’s skin, appetite, weight or the way your dog walks;
  • go back for any recheck your vet books.

Outlook

The outlook is guarded and tends to worsen as the dog ages and joint pain progresses [1]. In the largest case series, most dogs with a recorded outcome were put to sleep because the disease did not respond to treatment or the treatment caused problems [2].

These are statements about groups of dogs. They cannot predict how one dog will do. Talk to your vet about your dog’s care and comfort.

When to see your vet

See your vet if your dog has:

  • scaling, crusting or hair loss, especially in a young German Shorthaired Pointer [1];
  • itchy or sore skin [1];
  • a fever or swollen glands (enlarged lymph nodes) [1];
  • stiffness, lameness or a hunched stance [1][2].

The bottom line

Exfoliative cutaneous lupus is an inherited skin disease of German Shorthaired Pointers. Only a vet can tell it apart from other skin diseases that cause scaling and crusting.
