Psoriasis can appear in a number of forms, the most common being plaque psoriasis. Read on to learn all about the various types of this skin condition.
This form of psoriasis is characterized by raised, inflamed, red lesions covered by a silvery white scale. It’s usually found on the elbows, knees, scalp and lower back.
Pronounced GUH-tate, this kind of psoriasis often starts in childhood or sometime during the teens and 20s. It appears as small, red, individual spots on the skin, typically appearing on the trunk and limbs. These spots - named “guttate” for the Latin word meaning “drop” - are not usually as thick as plaque lesions.
This type of psoriasis is found in the armpits, groin, under the breasts and in other skin folds around the genitals and the buttocks. It appears as bright-red lesions that are smooth and shiny, and can prove to be easily irritated from rubbing and sweating because of its location in tender areas. Those who are overweight or have deep skin folds may find this kind of psoriasis especially uncomfortable.
This form, is characterized by white blisters of noninfectious pus surrounded by red skin. It may be localized to certain areas of the body, or it may cover nearly all of your body.
Possible triggers: internal medications, topical agents, overexposure to UV light, pregnancy, systemic steroids, infections, stress and sudden withdrawal of systemic medications or potent topical steroids.
This type of psoriasis is particularly inflammatory and affects most of the body. It may occur with von Zumbusch pustular psoriasis, and is characterized by widespread, fiery redness of the skin and the shedding of scales in sheets, rather than smaller flakes. The reddening and shedding of the skin are accompanied by severe itching and pain, heart rate increase and fluctuating body temperature.
