Inverse psoriasisPsoriasis is a noncontagious, chronic skin condition that produces plaques of thickened, scaling skin. The dry flakes of skin scales result from the excessively rapid proliferation of skin cells.
Inverse psoriasis (also known as intertriginous psoriasis) shows up as very red lesions in body folds. It may appear smooth and shiny. Many people have another type of psoriasis elsewhere on the body at the same time.
Inverse psoriasis is found in the armpits, groin, under the breasts and in other skin folds on the body.It is particularly subject to irritation from rubbing and sweating because of its location in skin folds and tender areas. It usually lacks the scale associated with plaque psoriasis due to the moist environment. It is more common in overweight people and people with deep skin folds.
Treatment can be difficult due to the sensitivity of the skin in these areas. Steroid creams and ointments are considered very effective, but they should not be occluded (covered) with plastic dressings. Because the skin is thinner in areas that typically have inverse psoriasis, the risk of side effects from topically applied medicine increases.
Obesity, diabetes, and heart disease are more common in people with psoriasis.
