Background and design: Psoriasis is an inflammatory skin disorder which affects both adults and children. Our purpose was to investigate clinical characteristics and the significance of predisposing factors in children with psoriasis. Materials and methods: Study group was composed of 117 children with psoriasis who were retrospectively evaluated from patient records. Results: 62% of patients were female, 38% were male. Median age was 8 years (1-15 years), and 62% of the patients were within 7-12 years of age. In patients' past medical history, drug intake in 7 % of the patients, upper respiratory tract infection in 13 % and family history of psoriasis in %10 of the patients were present. Group-A beta hemolytic streptococci was cultured from 25% of the throat swabs taken. Psoriatic lesions were plaque in type in 90 % of the patients. Lesions were mostly localized on scalp and trunk (93%). Involvement of the nails were estimated in 25 patients which mostly consist of pitting in 80 % of the patients. Conclusion: Childhood psoriasis mostly presents with plaque type lesions. Although correlation between throat infection and psoriasis could not be established in our study patients with positive culture results tend to have less recurrences.
