Types of Psoriasis

The type of psoriasis you have is determined by the appearance and location of the lesions. There are three main forms of psoriasis and a fourth which is uncommon and questionable as to its relationship to psoriasis.

Discoid Psoriasis:

In this, the most common form of psoriasis well defined margins appear around the disc like lesions or plaques. There may only be one or two lesions or there may be numerous lesions affecting large portions of the body. The smaller lesions often join up to form larger patches. This type of psoriasis often affects the scalp.

Guttate Psoriasis:

Guttate psoriasis often presents as the first sign of psoriasis. This psoriatic form appears as small, red, scattered, drop-like lesions usually on the trunk and limbs. They may disappear spontaneously or develop into scaly patches.

Flexural Psoriasis:

Also known as Inverse Psoriasis, this form of psoriasis is usually confined to the body folds where there is an increase amount of moisture. The condition may be confused with other conditions as the moisture level in the area results is the lesions losing their typical dry, whit scale.

The most common areas for this form of psoriasis are armpits, groin, under breasts and in the cleft of the buttocks.

Pustular Psoriasis:

It is not sure whether this form of psoriasis is actually psoriasis or whether it is a totally separate condition. It is less common than the other forms and most commonly affects the fingers and palms of the hands and toes and soles of the feet. It appears as numerous, small, sterile, non infectious pustules.

When it becomes chronic and inflamed the skin will become dry, scaly and sensitive. I may be isolated or in association with other forms of psoriasis.
