Overview. Dermatitis is a common condition that causes swelling and irritation of the skin. It has many causes and forms and often involves itchy, dry skin or a rash.
Subcorneal pustular dermatosis (Sneddon-Wilkinson disease)
Subcorneal pustular dermatosis is also known as Sneddon-Wilkinson disease. It is a rare condition, characterised by pustules that appear in crops over months or years. In some cases, subcorneal pustular dermatosis may be later diagnosed as generalised pustular psoriasis; generalised pustular psorasisis tends to be a more serious condition.
Erythema dyschromicum perstans (ashy dermatosis)
