Five Types of Psoriasis

There are five types of psoriasis, and each may be confused with other conditions (including rashes caused by allergies). At Spectrum Dermatology, a number of psoriasis treatments are available to offer patients relief and improve appearance. The most common sign that a rash is actually psoriasis is persistence. If you have a rash that doesn’t go away, it becomes inflamed, or begins to look like scales, it may be psoriasis.

Plaque Psoriasis

The five types of psoriasis all have different causes, show different symptoms, and require different treatments. The most common type is plaque psoriasis. It shows up as red or pink raised lesions (plaques) and silver-colored scales. Plaque psoriasis can be itchy, cause soreness, and may bleed if scratched. Plaque psoriasis can happen anywhere, but is most common on elbows, knees, lower back, and the scalp. Treatment usually includes topical and oral medications and/or laser/light therapy.

Guttate Psoriasis

The next most common type of psoriasis is guttate psoriasis. Around ten percent of psoriasis patients have this type of psoriasis. It looks like small, red sores usually on the trunk or limbs. The sores can look like dots, and many lesions have silver scales that are slimmer than plaque scales. Usually children and young adults get this type of psoriasis, which can be triggered by bacterial infections.

Inverse Psoriasis

Inverse psoriasis is most common in the armpits, genital area, behind the knees, below the breasts, and between the buttocks. There might be red patches, shiny and inflamed skin, but there are no scales. Soreness is common. Inverse psoriasis gets exacerbated in the summer and is most common in those who are overweight. Steroid cream is often recommended along with antifungal powders to keep the area dry.

Pustular Psoriasis

Pustular psoriasis is rare, and usually occurs in adults. Patches may occur on hands, feet, or large areas on other parts of the body. The skin looks red, inflamed, and white pus-filled blisters may form. This type of psoriasis may be caused by medication withdrawal, infections, pregnancy, stress, or too much UV exposure. Oral medication and nutritional supplements may be prescribed.

Erythrodermic Psoriasis

The rarest type of psoriasis is erythrodermic psoriasis. Three percent of psoriasis patients have this type of psoriasis. When it occurs, over 75 percent of the body has a red rash that will peel in sheets. It is very itchy and painful, and requires hospitalization.
