Psoriasis may take on many forms:

1. Psoriasis vulgaris

Common psoriasis or psoriasis vulgaris is the most common form of psoriasis. The disease manifests itself in the extension side of your elbows, knees and on the back above the buttocks. There you will get clearly defined, red symmetric blotches. Silver-grey skin flakes in varying sizes will form on these plaques. They are easy to remove.

Common psoriasis also occurs on other parts of the body. Often on the scalp. It is then known as psoriasis of the hirsute scalp or psoriasis capitis.
In the case of inverse psoriasis, or psoriasis inversa, the skin disease occurs in large skin folds such as the armpits, groin, beneath the breast or on the inside of your elbows. This form of psoriasis often attacks obese people. Your skin then becomes red and itchy but does not flake.

 

 

2. Psoriasis pustulosa
This form of psoriasis is very rare. One will get little liquid-filled blisters or 'pustels' which occur mainly on the palms of one’s hands or the soles of one’s feet. This form of psoriasis may be accompanied by fever.

3. Psoriasis guttala
Psoriasis guttala is an acute form of psoriasis. Generally the disease is a reaction to an inflammation - for instance of your throat - or acute stress. Little spots, no larger than 1 cm in diameter appear over the whole body - but especially across the trunk and the limbs. Drop psoriasis occurs mainly in children and young adults. The disease usually lasts only a few weeks and heals spontaneously.

4. Psoriasis unguum
Nail psoriasis occurs on one or all nails of your hands and feet. The nails then usually turn brown with little indentations in the nail plate. Sometimes the nail even comes loose.
5. Psoriasis ertrodermie
This form is extremely rare. It is a type of psoriasis which comes up suddenly and causes the whole body to turn bright red.
6. Psoriasis arthropatica
With this type of psoriasis you also have trouble with your joints.

 

What causes psoriasis?

It is presumed that an immunity system disorder lies at the base of psoriasis. This causes your skin cells to multiply much too quickly - up to six times quicker than normal. In this way your skin cells do not have enough time to mature. And your body rejects them prematurely. That makes your skin corneous, causing it to start flaking. Stress promotes psoriasis. If you have to deal with increased stress, psoriasis will flare up or the symptoms will exacerbate .
