The Occurrence of Inverse Psoriasis

Inverse psoriasis is characterized by smooth inflamed lesions in the body folds -- armpits, under the breast, skin folds of the groin, buttocks, and genitals. Large, dry, smooth, vividly red plaques occur in the folds of the skin near the genitals, under the breasts, or in the armpits. Inverse psoriasis is related to increased sensitivity to friction and sweating and may be painful or itchy.
