Psoriasis Symptoms
Psoriasis symptoms occur when the immune system mistakenly targets the bodys
own cells, causing skin cells
to replenish too rapidly. Overproduction of skin cells causes plaques (patches
of thick, raised patches of skin) to form since old skin cells are not able to
slough off quickly enough. Itching is the most commonly reported symptom of
psoriasis.
Doctors may find it difficult to diagnose psoriasis, because symptoms and
appearance often look like other skin diseases. It may be necessary to confirm a
diagnosis by examining a skin sample under a microscope. There are several forms
of psoriasis which have different characteristics and symptoms. Some of these
include:
- Plaque psoriasis - Skin lesions are red at the base and covered
by silvery scales. Most common on your knees, elbows, trunk, palms, soles
and scalp.
- Guttate psoriasis - Small, drop-shaped lesions appear on the
trunk, limbs, and scalp. Guttate psoriasis is most often triggered by upper
respiratory infections, for example, a sore throat caused by streptococcal
bacteria.
- Pustular psoriasis - Blisters of noninfectious pus appear on the
skin. Attacks of pustular psoriasis may be triggered by medications,
infections, stress, or exposure to certain chemicals.
- Inverse psoriasis - Smooth, red patches occur in the folds of the
skin near the genitals, under the breasts, or in the armpits. The psoriasis
symptoms may be worsened by friction and sweating.
- Erythrodermic psoriasis - Widespread reddening and scaling of the
skin may be a reaction to severe sunburn or to taking corticosteroids
(cortisone) or other medications. It can also be caused by a prolonged
period of increased activity of psoriasis that is poorly controlled.
- Psoriatic arthritis - Joint inflammation that produces symptoms
of arthritis in patients who have or will develop psoriasis.
Most often symptoms of psoriasis are mild, but for others it can be
disabling. If your skin condition is painful or makes performing routine tasks
difficult, talk to your dermatologist or doctor.
