Eczema craquelé

What is eczema craquelé?

Eczema craquelé is a common type of dermatitis that occurs as a result of very dry skin. It got its French name from its cracked appearance. It is also known as asteatotic eczema (lack of oil) or xerotic (dry) eczema.

The most common site is the shins, but eczema craquelé may occur elsewhere including upper limbs and trunk.

What causes eczema craquelé?

Eczema craquelé is mainly due to water loss from the stratum corneum. This occurs because of a breakdown of the skin barrier due to genetic predisposition and injury by environmental factors. These include:

  • Low humidity (winter, desert, high altitude, travel, use of dehumidifier or fan heater)
  • Excessive bathing especially using soaps and detergents.

Who gets eczema craquelé?

Eczema craquelé can occur in anyone with very dry skin.

  • It most often affects the elderly
  • It is also a complication of inherited and acquired forms of ichthyosis
  • Systemic causes include underactive thyroid (myxoedema), malnutrition (zinc and fatty acid deficiencies), severe weight loss and lymphoma
  • Drugs can cause asteatotic eczema, particularly retinoids (acitretin, isotretinoin), diuretics and protein kinase inhibitors

What are the clinical features of asteatotic eczema?

Eczema craquelé often has a distinctive crazy-paving appearance. Diamond-shaped plates of skin are separated from each other by red bands forming a network. There may also be scratch marks. It may start on one shin but soon spreads to affect the skin around both lower legs.

Severe eczema craqelé can lead to more severe secondary dermatitis with generalised redness, localised swelling and surface blistering. Like other forms of eczema on the lower leg, it can eventually result in widespread secondary disseminated eczema (autosensitisation).

What tests should be done?

Eczema craquelé is diagnosed by its appearance and tests are unnecessary in the majority of patients.

Thyroid function tests are appropriate if there are other signs to suggest hypothyroidism, such as dry thinning hair, weight gain, lethargy and slowness. If eczema craquelé is of recent onset and accompanied by excessive scaling (acquired ichthyosis), weight loss, fevers or general unwellness (malaise), the patient should be thoroughly investigated for an internal cause.

What is the treatment for eczema craquelé?

Eczema craquelé usually rapidly responds to treatment.

  • Consider factors that have caused dry skin: bathe less frequently, use a cream cleanser instead of soap, do not expose skin to direct heat.
  • Apply thick emollients and moisturisers such as petroleum jelly / petrolatum or oily cream several times daily – after a few days thinner ones such as non-ionic cream should be adequate.
  • Apply mild topical steroid cream or ointment to reddened skin for a few days; hydrocortisone cream or ointment is often sufficient.
  • A more potent topical steroid may be necessary if the eczema is severe.

Ensure the skin is not allowed to dry out again, as eczema craquelé is very likely to recur.
