What is Psoriasis?
Psoriasis is a skin disorder that is characterized by thick, red swollen patches covered with silvery white scales. These patches may often be found on the scalp, face, lower back, elbows, knees, hands, fingernails, toenails and soles of the feet. They may even develop in the inside of the mouth or on the genitals.
This condition causes the skin to itch and may be painful. Psoriasis is a debilitating, chronic disorder that affects the quality of life. There is no cure and people often experience flare-ups and remissions throughout their life. It often also leads to depression, stress and anxiety. Psoriasis affects men and women equally but may be more common amongst Caucasians.
There are different types of psoriasis including:
Plaque psoriasis may be distinguished by raised, red patches covered with silvery white scales. These scales are caused by a buildup of dead scales. This is the most common type of psoriasis and may occur on the scalp, elbows, knees or any other skin surface.
Guttate psoriasis appears as tiny, red dots and the lesions may have some scaling. Guttate psoriasis may occur after a bacterial or viral infection, or certain medications such as salicylic acid has been administered.
Inverse psoriasis is characterized by smooth, red patches without scaling. The affected area becomes irritated because of sweating and rubbing of the skin. This type of psoriasis occurs in the folds of the skin, specifically in the armpits, under the breast or groin.
Pustular psoriasis appears as blisters filled with pus on the skin. These blisters are not infectious and may be found on the hands and feet or may be spread all over the body.
Psoriatic arthritis approximately 10% of patients with psoriasis may develop a form of arthritis called psoriatic arthritis. Redness and swelling may be caused on the elbows, hands, knees, feet, hips and spine. It may result joint pain and stiffness.
