Psoriasis can present with many different appearances. It is a common, recurrent immune mediated disease of the skin and joints. It is found worldwide and has a strong genetic component. The scaling papules and plaques are circular with grey or silvery-white appearance. They usually appear on the scalp, elbows, knees,lumbosacral area and in body folds. The term Ostraceous psoriasis refers to the thickened plaques that have concave centers similar in shape to oyster shells.
