The major clinical forms of psoriasis are similar in children and adults. Chronic plaque psoriasis is the most common form of psoriasis in children. Guttate, pustular, and erythrodermic psoriasis are less frequent.
Chronic plaque psoriasis is characterized by the presence of well-demarcated, erythematous plaques with silvery-white, mica-like scale. In children with highly pigmented skin (Fitzpatrick skin type V or VI), erythema may be less prominent and plaques may appear violaceous or hyperpigmented.
•Sites of involvement
Children with psoriasis are more likely to present with psoriasis involving the face, scalp, or intertriginous skin than adults. Involvement of the diaper area (also known as “napkin psoriasis”) can be the initial manifestation of psoriasis in infants and young children.
