Psoriasis (colloquially known as psoriasis) is a benign, often chronic inflammatory disease of the skin. The cause is probably a disorder of the immune system.
The symptoms of psoriasis can be so mild that the affected person hardly notices them. In other cases, the quality of life of those affected can be severely restricted by a pronounced clinical picture. The appearance and localization of psoriasis can vary from person to person. In addition to the skin and nails, and in exceptional cases the mucous membrane, the joints can also be affected by psoriasis, which is known as psoriatic arthritis.
Psoriasis is not a contagious disease, but it can be inherited. Therefore, the risk of disease in children of affected individuals is higher than the risk in the average population. An estimated two to three percent of all Germans suffer from psoriasis. Psoriasis occurs in all age groups. Women are affected minimally less often than men.
