Picture of Inverse Psoriasis
Inverse psoriasis consists of bright red, smooth (not scaly) patches found in the folds of the skin. The most common areas are under the breasts, in the armpits, near the genitals, under the buttocks, or in abdominal folds. These irritated and inflamed areas are aggravated by the sweat and skin rubbing together in the folds. Yeast overgrowth, common in skin folds, may trigger the skin lesions of psoriasis.
