An important characteristic of pediatric dermatology is the relatively frequent occurrence of skin diseases in children, which makes their relatives worried about them. We retrospectively reviewed electronic records of patients under the age of 18 who were admitted to a state hospital dermatology outpatient clinic between January 1, 2015, and December 31, 2015. Clinical diagnosis, age, gender, and admitting dates of the patients were recorded into an electronic database. The mean age of participants was 13.51 ± 4.65 years (median=15, min=1, max=18 years). The most common diseases are adnexal diseases in 4570 (34.8%) patients.This was followed by infections-infestations (n=3057, 23.3%), papulosquamous and eczematous dermatoses (n=3009, 22.9%); hair, nail and mucous membrane disorders (n=760, 5.8%); pigmentation disorders (n=341, 2.6%), urticaria, erythema and purpura (n=284, 2.2%); pruritus (n=269, 2.0%); neoplasms of skin (n=227, 1.7%); disorders due to physical agents (n=176, 1.3%); disorders of keratinization (n=55, 0.4%), respectively. We believe that the frequency and severity of children's skin diseases can be reduced by establishing appropriate preventive health policies and dissemination of educational programs, and it will be useful to organize training programs on common pediatric skin diseases, especially to primary care physicians.
