Skin rash can suddenly appear at different parts of the body and look quite different: for example, spots, blisters or scales can form on the skin. Infectious diseases such as chicken pox or measles can be behind the skin rash. There are also allergies or various skin diseases including psoriasis or neurodermatitis. Here you will learn what skin rash mean and how it is treated.
The human skin consists of about two billion skin cells, which protect the body against pathogens, sun radiation, sun exposure, excessive heat loss, dehydration and also from overheating. The skin is also the largest organ of the body. Skin covers an area of about two square meters and weighs a total of ten kilos in an adult human being.
The skin usually responds immediately and visibly to external and internal influences – with a rash that can also extend to larger areas of the skin. The skin rash may consist of colored spots, liquid-filled vesicles, pustules, wheals or nodules. Based on the appearance of the rash, dermatologists can often close the cause. Itchy rash is not uncommon – the itching is a frequent concomitant symptom. The rash can also cause burns or pain or a feeling of warmth.
