    Atopic dermatitis is a chronic inflammation of the skin of obscure origin. Very common in children, it tends to mitigate with age. The itchiness can be very persistent and there is no real cure, although complications can be avoided with good skin care.


    Atopic dermatitis is also known as eczema. It usually has an intermittent course with flares and remissions of unknown origin.
