The main objective of this study was to determine the prevalence of psoriasis in children less than 16 years including in relation to the total number of consultations for this disease in the dermatology service at Pediatric Hospital  "Niño Jesus", since July 2008 to August 2009. During this period of time 5753 dermatological consultations were attended,  children and adults as well. In 5753 dermatological consultations, 115 were for psoriasis patients, of whom 26 were under 17. We studied 26 children between 3 months and 16 years. Women being the most affected with a female man 4,2: 1. The most affected age group was between 9 and 13. The precipitating factors, both external and systemic, may raise psoriasis in predisposed individuals from the genetic standpoint, in this study infections were observed in 8 patients (30.77%), psychogenic stress in 2 of them (7, 7%), and drugs also in 2 (7.7%) The clinical variant most common were the vulgar-plaques and guttate in 12 patients (46.15%) and pruritus the most common symptom in 18 (69.23%). The 88.46% of the cases were successfully treated with topical treatment and only 11.54% required more aggressive treatment. We conclude that this age group is frequently affected by psoriasis with prevalence in relation with total visits for the pathology of 22.6%.
