Scalp Psoriasis

Plaque psoriasis
The vast majority of people with psoriasis have plaque psoriasis. Typically, characteristics include patches on the elbows, knees, scalp and lower back, but it can be found on any area of the skin. Each patch usually looks like a red raised patch with overlying flaky white scaly surface that feels rough. The patches are well defined, can be single or multiple occurrences, and can vary in size (one to over twelve inches). The picture in the top left corner of the page accurately reflects the appearance of plaque psoriasis.

Nail psoriasis
This occurs in many people with plaque psoriasis. However it may also occur alone without the patches. Tiny pits occur in the nails, sometimes causing the nail to separate from the nail bed.

Guttate psoriasis
This form of psoriasis is characterized by small patches (similar to Plaque psoriasis) occurring in several areas of the body. It typically occurs following a throat infection (streptococci), and children and teenagers are particularly prone. The rash eventually disappears in most cases, but some children go on to develop plaque psoriasis, which may remain indefinitely. Some children, who are prone to tonsillitis, may develop Guttate psoriasis with each attack.

Inverse psoriasis
This form is characterized by areas of skin in folds or creases (flexures), becoming dry with large smooth red patches. It is most commonly found in the armpits, groin, between the buttocks and under the breasts. Because these are sites of sweating and friction the areas can become itchy and very uncomfortable, especially in hot weather.

Erythrodermic psoriasis
This form is characterized by the entire body periodically becoming red, inflamed and scaly. This is a very rare condition, which compromises the body’s temperature and fluid balance.

Pustular psoriasis
This form is very rare: It is characterized by either widespread areas of red skin with pus-filled blisters or localized areas, particularly the palms of the hands and soles of the feet or the fingers or toes.
