Flexural Psoriasis is a non-infectious auto-immune disease, caused by activation of T-cells within the skin. It is more frequent and severe in people who are overweight because it is in the skin folds where it is particularly prone to irritation from rubbing and sweating. It is a chronic disease characterized by thick, red, silvery, scaled patches of skin. Flexural Psoriasis is a form of psoriasis found in the armpits, groin, under the breasts and in other flexion creases such as those around the genitals and buttocks. It can occur at any time of life, but most commonly appears in the early 20s, and can occur in both men and women and tends to occur more in fair skinned people. Due to the moist nature of the skin folds the appearance of the psoriasis is slightly different. It tends not to have silvery scale, but is shiny and smooth. There may be a crack in the depth of the skin crease. Flexural psoriasis is more frequent and severe in people who are overweight because it is in the skin folds where it is particularly prone to irritation from rubbing and sweating.

Most patients experience depression, which in turn increases the symptoms of Psoriasis, and in return leads to more anxiety and stress. The plaques are sometimes infected with the fungi candida albicans. It sometimes appears at the site of injuries or scars. Around 6 per cent of the people who have psoriasis also get psoriatic arthritis in the joints. Psoriatic arthritis primarily occurs in fingers and toes, but is also quite common in the back bone. Psoriasis is a chronic disease, which means you may have it for months or years. However early treatment may minimise the severity of the disorder. Flexural psoriasis responds quite well to topical treatment but often recurs. Weak topical steroids may clear flexural psoriasis but it will usually recur sometime after discontinuing treatment. Systemic agents are rarely required for limited flexural psoriasis and phototherapy is relatively ineffective because the folds are hidden from light exposure.
