The National Psoriasis Foundation works to find a cure for psoriasis and psoriatic arthritis and to eliminate their devastating effects through research, advocacy and education. There are five types of psoriasis: plaque, guttate, inverse, pustular, and erythrodermic. The most common form, plaque psoriasis, is seen as red and white hues of scaly patches appearing on the top first layer of the epidermis (skin). Let me take psoriasis as an example of a chronic non-contagious dermatological disorder associated with cosmetically disfiguring skin lesions, often with severe social impact on the patient. We have no explanation for distribution – psoriatic plaques are normally over the knees and elbows; but then why is guttate psoriasis predominantly on the trunk? Moderate to severe disease is with a PASI 10 either alone or with a DLQI 10. For the trust that means about 5,400 cases a year have to be red flagged, that is seen within two weeks of referral for query malignant melanoma, or changing mole, and does not include other red flag items.
