BACKGROUND Paediatric dermatology is a unique subspecialty in that child is not a miniature adult. Paediatric dermatoses differ from that of the adults in clinical presentation, treatment and prognosis. Various studies from India have shown infections and infestations to be the most common paediatric dermatoses. This study was planned to determine the epidemiological pattern of common noninfectious dermatoses in our paediatric patients as no such data are available from this part of the country. A cross-sectional study was undertaken to study the prevalence of the noninfectious dermatoses in all the new paediatric patients attending the Skin Outpatient Department (OPD) at Villupuram Medical College over a period of three years. MATERIALS AND METHODS A total number of 550 children in the age group ranging from newborn to 12 years with noninfectious dermatoses attending the OPD for the first time were enrolled in the study. RESULTS Physiological changes of skin was the most common dermatoses in the newborn age group, while eczema was the most common dermatoses in infants, preschool and school going children. In the infants, eczema was followed by pigmentary disorders, mongolian spots, vascular nevi, ichthyosis, epidermolysis bullosa, alopecia areata and papular urticaria in the order of prevalence. Among preschool going children, eczema was followed by papular urticaria, papulosquamous disorders, pigmentary disorders, hair disorders, nevi, drug reactions, keratinisation disorders, urticaria, etc. In the school going age group, eczema was followed by papulosquamous disorders, pigmentary disorders, papular urticaria, nutritional disorders, ichthyosis, nevi, miliaria, drug reaction, hair disorders, photodermatoses, urticaria, collagen vascular disease and vascular nevi in the order of prevalence. CONCLUSION Eczema, papulosquamous disorders, papular urticaria, pigmentary disorders seem to be the most common noninfectious dermatoses in children. However, further studies in large scale are required to throw more light on the prevalence of these conditions.
