Types of Psoriasis

There are many types of psoriasis. Plaque Psoriasis is the more common.

Plaque psoriasis

This is most often seen as red, thick, patches of skin covered with silvery scales. You may also experience chnages to finger and toe nails, so that they look pitted, thicker than normal, or can even become loose and fall off.

This kind of psoriasis can develop anywhere on the skin, but is most often seen on the elbows, knees, scalp, lower back and the cleft of the buttocks. It is also sometimes called "psoriasis vulgaris" (meaning common, not vulgar).

Guttate psoriasis

Is commonly characterised by small teardrop-shapped, pink, scaly skin patches.

These numerous spots of psoriasis usually appear on the trunk of the body, and sometimes the palms of the hand and/or soles of feet.

Flexural (inverse) psoriasis

This is commonly seen as red, smooth skin patches, without the typical white scales.

It usually affects the armpits, groin area, under the breasts and other skin folds.

Pustular psoriasis

Usually appears as raised bumps (yellow-white "blisters") that are filled with non-infectious pus (pustules) surround by tender red skin.

This type of psoriasis primarily affects the palms of hands, and/or soles of feet, but is occasionally widespread. Patches can occur randomly on any part of the body. People with pustular psoriasis are often systemically unwell and require urgent medical attention.

Palmoplantar psoriasis

This type of psoriasis can be associated with chronic plaque psoriasis and is usually localised to palms of the hand and soles of the feet. It is characterised by well-defined, red, scaly plaques that are similar to plaques found on other areas of the body.

Erythrodermic psoriasis

This tends to be characterised by intense redness and scaling and for some people may be associated with severe itchiness, swelling and pain.

This type of psoriasis involves widespread inflammation over large areas of the body surface.
