Inverse Psoriasis

Inverse psoriasis (as you can probably guess) is so named because its lesions are the opposite of those that appear on other psoriasis sufferers. Instead of rough, scaly plaques, inverse psoriasis sufferers have patches of shiny and smooth skin in their affected areas. These lesions usually cover a large area of the body, and are quite visible thanks to a bright red color. Inverse psoriasis is also referred to as flexural psoriasis because it affects the soft, flexible parts of the body.

This type of psoriasis commonly afflicts overweight people. Bodies that carry extra weight have more places for psoriasis patches to spring up. These patches can occur in areas where the skin creases or folds. Lesions frequently emerge in the armpits, under sagging breast tissue, between the buttocks, and in the groin area.

It may be hard to exercise or function normally because of these lesions. Rubbing and sweating usually cause irritation, and can make the simple act of walking uncomfortable. People with flexural psoriasis may also experience chafing and thinned skin. The good news is that inverse psoriasis cannot be spread by skin-to-skin contact.

Treatments for Inverse Psoriasis

Inverse psoriasis typically responds well to topical skin treatments, such as applications of steroid creams and ointment or products containing vitamin D3 derivatives, retinoids, and coal tar. Medicines designed to treat fungal and yeast infections may also be prescribed since skin folds have a tendency to suffer from these types of infections. Women and middle-aged older people are more apt to be susceptible to inverse psoriasis.
