There are 5 types of psoriasis: plaque, inverse, guttate, pustular and erythrodermic. Here we indicate the characteristics of each one:
- PLAQUES PSORIASIS: it is the most common type. It is characterized by inflamed reddish lesions, covered by silvery scales. It often affects the elbows, knees, and scalp. However, it can affect any part of the body.
- INVERSE PSORIASIS: in this type, the lesions are smooth, shiny and bright red, but don’t have scales. In addition, irritations from rubbing and sweating are common, as they are found in the body skin folds. Therefore, it is common to have it in the armpits, under the breasts, and in other skin folds as it is around the genital area.
- GUTTATE PSORIASIS: causes small red spots isolated on the skin. Guttate psoriasis lesions tend to occur on the trunk and extremities, and usually are thinner than the ones from the plaque psoriasis.
- POSTULAR PSORIASIS: affects mostly to adults and is characterized by the appearance of pus-filled bumps on the hands and feet. These lesions are usually white, containing uninfected pus surrounded by a reddish on the skin.
- ERYTHRODERMIC PSORIASIS: is a rare but very dangerous form of psoriasis that usually requires hospital admission. It is characterized by an intense red, hot and a lot of scales in the skin. Usually, this redness and scales are accompanied by intense pain and itching, fast pulse and abrupt changes in body temperature. Erythrodermic psoriasis causes a loss of fluids and proteins that can be very dangerous.
