What causes inverse psoriasis?

Dr. Mehmet Oz, MD

Flexural psoriasis (also called inverse psoriasis) is one of the five main types of the autoimmune condition psoriasis. Though doctors do not completely understand what causes psoriasis, they do know that it develops when your immune system begins producing skin cells too fast.

According to the National Psoriasis Foundation, researchers have discovered that at least 10% of the population has a gene that makes them more likely to develop psoriasis. But only 2% to 3% of those people actually do develop it. Experts say this means there must be some combination of heredity and environmental triggers that causes the condition.

Though scientists do not know all the triggers that might lead someone to develop psoriasis or have an outbreak, they do know that stress, injuries to the skin, strep infection, and certain medications can play a role. Flexural psoriasis also seems to be more prevalent in people who are overweight.

Inverse psoriasis is the result of a disorder of the immune system. White blood cells, or T-cells, assist the immune system in protecting your body from disease and infection. However, in the case of psoriasis, T-cells begin going after the body's own healthy cells. This causes red, inflamed skin patches on the skin. These patches often appear wherever there are skin folds such as under the breast area, around the genital area, and near the armpits.
