Pediatric Dermatitis Seborrhoica - A Clinical and Therapeutic Review

Area of Science:

• Dermatology
• Pediatrics
• Immunology

Background:

• Pediatric seborrheic dermatitis (DS) is a prevalent inflammatory skin condition affecting infants and adolescents.
• It is distinct from atopic dermatitis, with a global prevalence potentially reaching 10% and a slight male predominance.
• The exact causes are unknown, but involve endogenous/exogenous factors, skin microbiome alterations, and innate immune responses.

Purpose of the Study:

• To review the clinical and therapeutic aspects of pediatric seborrheic dermatitis.
• To highlight the role of skin microbiome and inflammatory pathways in DS pathogenesis.
• To discuss current and emerging treatment strategies for pediatric DS.

Main Methods:

• A narrative review of existing literature on pediatric seborrheic dermatitis.
• Analysis of clinical presentations, epidemiological data, and etiological factors.
• Evaluation of current and potential future therapeutic interventions.

Main Results:

• Pediatric DS presents in various subtypes, from localized to disseminated forms, with risks of complications like erythroderma.
• Key factors include skin microbiome dysbiosis (increased Malassezia spp. and bacteria) and impaired skin barrier function.
• Current treatments involve antifungals and mild corticosteroids, with targeted therapies under development.

Conclusions:

• Pediatric DS is a significant differential diagnosis in pediatric dermatology.
• Advances in understanding pathogenesis are paving the way for novel, targeted treatments.
• Improved management strategies are anticipated due to a deeper insight into DS.
