Inverse Psoriasis

Inverse psoriasis (also known as flexural psoriasis) occurs in the creases and folds of the skin, such as the armpits, groin and under the breasts. The lesions are characterised by smooth, well defined red patches, but scaling is generally minimal or absent.

Inverse psoriasis is commonly seen in people who are overweight, as the condition is aggravated by the friction of rubbing skin and trapped perspiration in skin fold areas.
