What is Inverse Psoriasis?

Inverse or Flexural psoriasis is localized in the flexural surfaces of the skin, e.g., armpit, groin, under the breast, and other skin folds. Typically, it appears as smooth inflamed lesions without scaling and is particularly subject to irritation due to rubbing and sweating.

This type of psoriasis is often white in color, appears softened as if soaked by water, and may resemble a fungal infection. There is very little scaling, although the patches are inflamed and can be very sore. Appearing as it does in the folds of the skin, it is moister than other forms of psoriasis, and can be more uncomfortable physically.

Flexural psoriasis rarely occurs by itself. It is more likely to accompany common plaque psoriasis.

Psoriasis sufferers in their middle years or old age are more susceptible to this type of psoriasis as are people who are overweight and have more folds of skin.
