Newborn skin: Part II. Birthmarks.

Area of Science:

• Pediatrics
• Dermatology
• Genetics

Background:

• Birthmarks are common in newborns, causing parental anxiety.
• Current management guidelines often rely on expert opinion rather than robust evidence.
• Distinguishing benign from potentially serious birthmarks is crucial for appropriate care.

Purpose of the Study:

• To provide an overview of common newborn birthmarks.
• To outline evidence-based management and treatment strategies for various birthmarks.
• To highlight concerning signs requiring further investigation.

Main Methods:

• Review of existing literature and clinical guidelines.
• Categorization of birthmarks based on clinical presentation and risk.
• Emphasis on diagnostic evaluation and treatment options.

Main Results:

• Most birthmarks, including dermal melanosis, hemangioma of infancy, port-wine stains, and nevus simplex, are benign and may not need treatment.
• Large congenital melanocytic nevi warrant evaluation for removal.
• Specific skin markers indicate potential spinal dysraphism, necessitating imaging (MRI/ultrasonography).

Conclusions:

• Family physicians need to be knowledgeable about birthmark diagnosis and management.
• Early identification of high-risk birthmarks is essential for timely intervention.
• Cosmetic laser treatments offer effective options for benign vascular and pigmented lesions.
