Newborn Skin: Part II. Birthmarks

Area of Science:

• Dermatology
• Pediatrics
• Neonatology

Background:

• Birthmarks in newborns are common and require accurate classification for appropriate management.
• Understanding different birthmark types, such as vascular and melanocytic lesions, is crucial for pediatric care.

Purpose of the Study:

• To provide a classification of common newborn birthmarks.
• To outline management strategies for various neonatal skin conditions.
• To identify birthmarks that may indicate underlying developmental abnormalities.

Main Methods:

• Review of current literature and clinical guidelines for neonatal birthmark management.
• Classification of birthmarks into vascular, melanocytic, and those associated with nervous system abnormalities.
• Description of treatment modalities and referral criteria for specific conditions.

Main Results:

• Nevus simplex is a benign capillary malformation.
• Nevus flammeus can be treated with pulsed dye laser before age one.
• Infantile hemangiomas require systemic beta blockers for significant complications.
• Dermal melanocytosis is benign.
• Congenital melanocytic nevi require pediatric dermatology referral if large or multiple.
• Skin markers of occult spinal dysraphism necessitate imaging.

Conclusions:

• Accurate birthmark classification guides appropriate clinical management in newborns.
• Timely intervention with therapies like laser or beta blockers can improve outcomes for certain vascular lesions.
• Vigilance for potential underlying conditions, such as spinal dysraphism, is essential based on specific skin markers.
