RESUMO
BACKGROUND: Few epidemiological studies are available on childhood psoriasis. METHODS: Between 2005 and 2008, information was collected about all children diagnosed with psoriasis in the Pediatric Dermatology Unit of Andreas Sygros Skin Hospital, in Athens, Greece. RESULTS: A total of 125 children with psoriasis were examined, the male to female ratio was 1.4:1 and the peak age of onset was in the 9- to 10-year-old age group. Only 16% of the patients had a positive family history. Plaque type psoriasis was the most prevalent type at presentation with 56.8% of the children affected, followed by scalp involvement (33.6%). The limbs were the most prevalent site of involvement (70 children, 56%), followed by the body (59 children, 47.2%) and scalp (60 children, 48%) equally affected. Most of the children had <5% of their skin affected by psoriasis (53.2%). Age of onset had no influence on the severity of the disease (P=0.107), whereas a positive correlation was found with sex and severity of the disease, with male patients being more severely affected (P=0.008). Family history did not influence the age at presentation (P=0.68). Topical steroids were used in most commonly followed by keratolytics, calcipotriol, topical tacrolimus and topical pimecrolimus. CONCLUSION: Our study reflects the patterns of presentation of childhood psoriasis in sunny countries like Greece.
