A comparative study of pediatric onset psoriasis with adult onset psoriasis.

Psoriasis in childhood is not uncommon. We report data collected from 223 pediatric onset and 484 adult onset psoriasis patients. In the pediatric onset psoriasis patients (POPPs), prevalence of family history was 68.2% compared to 54% in the adult onset psoriasis patients (AOPPs). Also we noticed that exacerbation of psoriasis induced by precipitating factors such as stress (50.4% in POPPs, 42. 7% in AOPPs), pharyngitis (27.9% in POPPs, 12.2% in AOPPs), and trauma (49.6% in POPPs and 38.9% in AOPPs) were more frequent in POPPs. Our data show that the frequency of spontaneous remission in POPPs was 35.3% compared to 24.3% in AOPPs. A disfiguring skin disease in childhood may have profound emotional effects. Childhood psoriasis needs special attention. To achieve a prolonged remission it is essential that children with psoriasis and their parents have an understanding of the exogenous and endogenous factors responsible for the increased morbidity of psoriasis.
