Pediatric Dermatitis Seborrhoica - A Clinical and Therapeutic Review

Abstract

Abstract Pediatric dermatitis seborrhoica (DS) is a common inflammatory disorder of infancy and adolescence distinct from atopic dermatitis. We performed a narrative review on clinical and therapeutic aspects of the disease. The prevalence varies geographically and can reach up to 10%. There is a slight male predominance. Although etiopathology is not well known, both endogenous and exogenous factors contribute. Skin microbiome and its interaction with sebaceous gland function is crucial. The inflammatory pathways include innate immune function and skin barrier disturbances. Malassezia spp. and certain bacteria are increased in lesional skin. DS develops in different clinical subtypes, from localized cephalic to disseminated disease with a risk of erythroderma and eczema herpeticatum. Treatment consists of skin care and topical and rarely systemic medical therapy. Cornerstones of treatment are antifungals and mild corticosteroids. Targeted treatment is on the horizon. Pediatric DS is a common disorder important in the differential diagnosis of skin problems in infants and and children. Due to better understanding of its pathogenesis, new treatment options are developed.
