Asteatotic eczema causes dry, itchy, scaly skin and is most common in older people, particularly men in their 60s. It can be caused by environmental factors, medications, and medical conditions. Treatment includes moisturizers and avoiding hot water and harsh skin products. Humidifiers and proper hydration can also help prevent outbreaks.
Asteatotic eczema, also known as xerosis and eczema craquele, is a condition in which the mucous membranes of the skin become abnormally dry. It mainly affects the skin on the legs and arms, although it has also appeared on the trunk and hands in some cases. The most common symptoms are itchy, dry, red, scaly skin. There may also be small cracks in the affected areas.
Due to the reduced production of the sweat and sebaceous glands over time, older people tend to have drier skin. For this reason, it is the age group that is most likely to develop asteatotic eczema. The condition is particularly common among men in their 60s. Although the overall average age for people with asteatotic eczema is 69, younger patients have had the condition.
Environment, diet, medications, cleaning products, and irritating fabrics such as wool can cause or contribute to asteatotic eczema. Cold weather can increase the risk of getting sick from moisture loss in heated interior spaces. Using degreasing products such as cleaners and solvents can also cause irritation which can lead to an outbreak. A deficiency of zinc, linolenic acid or essential fatty acids can also be a cause. Diuretic and antiandrogen therapy drugs may contribute to the problem.
There are several medical conditions that can lead to asteatotic eczema. These include breast cancer, malignant lymphoma, colorectal cancer, and large cell lung cancer. Conditions that reduce sweating, such as thyroid disease and some neurological disorders, can also cause asteatotic eczema. There have been a few cases where radiation has played a role in the development of the condition.
Mild cases of asteatotic eczema can usually be treated with specially prescribed moisturizers. These drugs typically use lactic acid and urea to treat the condition. An effective method of application is to take a bath and then apply the moisturizer to damp skin. Patients are also often advised to avoid using soap on the affected area. Severe cases, which may include extreme itching and inflammation, may require the application of topical steroids.
The best ways to avoid asteatotic eczema are to limit exposure to water, avoid bathing in excessively hot water, and choose gentle skin cleansing products without fragrances or dyes. Using a humidifier, particularly during cold weather, can increase the humidity in the air and reduce the chance of an outbreak or a recurrence of the condition. Avoid dryness by hydrating properly, and using petrolatum-based moisturizers can also help keep your skin healthy.
