Plaque psoriasis
is the most common type of psoriasis. It is expressed by red, inflamed patches that cover areas of the skin. These patches are often covered with whitish-silver scales or plaques, which are commonly found on the elbows, knees, and scalp.
Guttate psoriasis
typically affects children and young adults. This type is expressed by small pink teardrop-shaped spots, which appear on the torso, arms, and legs.
Pustular psoriasis
is an uncommon form of psoriasis which mostly affects adults. It appears as clearly defined, raised bumps that are filled with a white, thick fluid. This infected exudates is commonly referred to as pus. Pustular psoriasis may precede, accompany, or follow the standard form of plaque-type psoriasis.
Inverse psoriasis
affects the skin folds (the areas of the body where skin rubs against skin). It can appear under the arms, under a woman’s breasts, or in the groin or inner thigh area. It looks like a red, shiny, smooth rash. People with inverse psoriasis often have another form of the disease, such as plaque psoriasis. Unlike plaque psoriasis which covers large parts of the body, inverse psoriasis may be limited to smaller patches.
Erythrodermic psoriasis
is a severe type of psoriasis, however, very rare. The main symptom appears as fiery red skin from head to toe. The skin is also covered in scales and peels off in large pieces. It can be very painful and itchy. If you think you may have Erythrodermic psoriasis, consult with your doctor right away.
