What is plaque psoriasis? Is it different from psoriasis?
My friend is having scaly, itchy lesions and has been diagnosed as plaque psoriasis. What is it and is it different from psoriasis ?
@vikrant Psoriasis, which manifests most often as plaque psoriasis, is a chronic, relapsing, inflammatory skin disorder with a strong genetic basis. Plaque psoriasis is rarely life threatening, but it often is intractable to treatment.
Psoriatic plaques are characterized as follows:
Raised and easily palpable - Owing to the thickened epidermis, expanded dermal vascular compartment, as well as infiltrate of neutrophils and lymphocytes
Irregular to oval in shape
One to several centimeters in size
Well defined, with sharply demarcated boundaries
Very distinctive rich, full red color; lesions on the legs sometimes carry a blue or violaceous tint
