MEDICAL DERMATOLOGY I ECZEMA
Eczema refers to a group of skin conditions that causes itchy and inflamed patches of skin. There are many types of eczema, including:
- Contact dermatitis – this is normally caused by contact with irritants or allergens. The inflammation normally goes away when the irritant or allergen is removed.
- Nummular eczema – this type of eczema causes round, coin-like spots on the skin. Symptoms of nummular eczema include spots that may be itchy or scaly.
- Dyshidrotic eczema - this is a type of eczema that results in small blisters forming on the hands and feet.
- Atopic dermatitis – this is the most common type of eczema that usually develops by the age of 5 and causes severely itchy rashes that come and go. The main symptom of atopic dermatitis is itchiness. Scratching in response to an itch can lead to many skin changes being seen. The itch can be severe enough to start interfering with your sleep, causing tiredness and irritability. The affected skin is usually red and dry and has scratch marks that may be accompanied by bleeding. Often, a skin rash can form in the creases of the elbows or knees but can occur anywhere. When atopic dermatitis is very active small water blisters may develop (usually on the hands and feet) and weep during a flare-up.
