People with psoriasis have a buildup of skin cells on various parts of their body. These cells appear dry with silvery plaques within reddened patches. This autoimmune condition causes the life cycle of skin cells to speed up so that there is an accumulation of roughened dead cells that frequently appear on elbows, knees or the scalp.
People with psoriasis are also at risk of developing other serious chronic health conditions such as cardiovascular disease, diabetes, cancer and psoriatic arthritis.
There are five main types of psoriasis, and two other associated ones that some consider to be additional types of psoriasis.
1) Plaque Psoriasis
Plaque psoriasis is the most common form, according to Psoriasis.org. Raised, thickened red patches with silvery white-colored cells build up on the skin anywhere on the body. The plaques may itch, or be painful and bleed.
2) Guttate Psoriasis
Guttate psoriasis is more common in children and young adults, and may be set off by a strep infection. It appears on the skin as small dot-like sores, covering the trunk, arms and legs. A fine silvery layer of cells may form on top of the sores.
It is possible to have a single episode of this form of psoriasis, or to have repeated episodes. Psoriasis.org says that about 10 percent of those people who have psoriasis have this form.
3) Inverse Psoriasis
Inverse psoriasis appears as reddened, inflamed areas in skin folds such as behind the knee, under the breast, and around the genitals. This form of psoriasis is worsened by friction, sweat and obesity, and lacks the scales that are present in other forms of psoriasis. Treatment may include topical steroids, anti-yeast or fungus medications.
4) Pustular Psoriasis
Pustular psoriasis can occur in patches or in small areas. It appears as white blisters filled with non-infective pus of white cells a few hours after the skin has become reddened and tender.
It is thought that this form of psoriasis may be triggered by a variety of causes such as after a drug reaction, the withdrawal of certain systemic drugs, pregnancy, and even by stress. The blisters dry out and disappear after a few days, but may reoccur every few days or weeks.
5) Erythrodermic Psoriasis
Erythrodermic psoriasis is a rare, severe form of psoriasis which covers the body with a red, peeling rash that may burn or itch intensely. Psoriasis.org states that it affects “only 3 percent of people who have psoriasis during their life time. It generally appears on people who have unstable plaque psoriasis.”
The two other associated types are scalp and nail psoriasis.
-Scalp Psoriasis
Scalp psoriasis has red, itchy areas with silver whitish scales on top of the affected skin. This form of psoriasis may extend beyond the hairline, and can bleed if the scales are removed. Psoriasis in children often appears first as scalp psoriasis.
-Nail psoriasis
Nail psoriasis can appear as pitting and abnormal growth on fingers or toenails. The nails can become loosened and separate from the nail bed or they can grow abnormally and become discolored. Nail psoriasis typically occurs along with another type of psoriasis.
