Types of psoriasis

Psoriasis is classified according to its manifestations and the place of occurrence:


Manifests itself in the form of red, demarcated deposits covered with scales. It most commonly attacks the scalp, elbows, knees, lower back and gluteal regions. These are usually the most mechanically stressed skin areas; this is typical for the occurrence of psoriasis. The nails on the hands and feet may turn yellow or become pitted. The dissemination of fresh psoriasis is not aesthetically pleasing, but the spots usually do not itch or hurt too much, and do not cause the patient a lot of discomfort.


Occurs mainly in children and adolescents and manifests itself in the form of small deposits, which are sometimes raindrop or teardrop shaped.


Occurs in the armpits, neck, under the breasts, in the navel, groin, genital area and the anus. It manifests itself in the form of strong red, dry or oozy deposits located mostly in the skin folds..


This form is quite different from other types of psoriasis. It manifests itself in the form of blisters on the palms and soles. It is usually accompanied by severe fever and chills. This severe form of psoriasis often requires hospitalisation.

Systemic and erythrodermic

This is the most severe form which requires hospitalisation. The manifestations are spread throughout the body, and the deposits are usually painful and itchy. It is accompanied by increased temperature and fever, chills, dehydration, loss of proteins and edema.


Attacks the small joints of the hands and feet. It manifests itself through swollen joints, pain and morning stiffness. It can also affect large joints, typically the shoulders or knees, spine and ligaments. This form of psoriasis should be treated by a rheumatologist.
