[What's new in pediatric dermatology?]

Area of Science:

• Pediatric Dermatology
• Dermatopathology
• Clinical Research

Context:

• The year 2009 saw significant advancements in understanding and treating pediatric skin conditions.
• Existing literature was expanded with new research across multiple dermatological subspecialties.
• This review synthesizes key findings from the 2009 literature.

Purpose:
