Abstract

Abstract: Our aim was to describe the types of psoriasis seen in a large series of patients presenting to a tertiary referral pediatric dermatology department using a classification system combining conventional terminology and additional categories based on the site and characteristics of the rash. A total of 1262 patients seen consecutively in the dermatology department of the Royal Alexandra Hospital for Children, Sydney, Australia, between 1981 and 1995 are described and classified according to the pattern of psoriasis at the time of presentation. Additional information recorded included family history, facial involvement, and history of a psoriatic type of diaper rash in infancy. The ages of the children ranged from 1 month to 15 years. There was an equal gender distribution and a high rate of positive family history at 71%. Twenty-six percent of children had a history of a psoriatic diaper rash and facial involvement occurred in 38% of children. Plaque psoriasis was the most common type overall, affecting 430 patients (34%). Three hundred forty-five children were less than 2 years of age, and this is the largest series of children with psoriasis in this age group presented to date. An entity defined by us as psoriatic diaper rash with dissemination was the most common type of psoriasis in the less than 2-year age group, affecting 155 (45%) patients. This large series offers information on the manifestations of psoriasis in childhood, but is particularly useful in examining the previously less well-described infant age group. The classification used is proposed as a practical way to describe psoriasis in children, particularly with respect to future descriptive studies.
