Common Baby Birthmarks and Rashes Explained

Gazing at your newborn, you might notice small marks or discolorations on their skin. These baby birthmarks and rashes are often harmless. Some appear at birth, while others develop shortly after. Though most need no treatment, understanding them helps you know when to see your pediatrician.

Vascular Birthmarks: Red, Pink, and Blue Spots

These birthmarks result from extra or malformed blood vessels. They’re usually warm and visible on the skin.

Nevus Simplex (“Angel Kisses” and “Stork Bites”)

These flat red or pink patches are common in newborns. They appear on the forehead, eyelids, or neck. Most fade by toddler age and are harmless. However, talk to your pediatrician if they grow or look unusual.

Port Wine Stains

These dark pink or red patches are larger and don’t fade over time. They grow as your child grows. If found near the eyes or forehead, your doctor may check for related conditions. Laser treatment can help lighten them.

Infantile Hemangiomas

These red or blue bumps grow rapidly in early weeks. They usually shrink around age one. Some need early treatment to prevent long-term issues. Always consult your doctor if a mark grows fast or changes.

Congenital Hemangiomas

Present at birth, these marks can look purple or blue with red veins. Some fade quickly, while others remain. They may be removed later if needed, but often cause no problems.

Venous Malformations

These blue or purple marks appear later and may become painful. They might grow with activity or during puberty. Treatments like compression garments or surgery can help if symptoms appear.

Pigmented Birthmarks: Brown, Black, and Grey Spots

These marks come from pigment-producing skin cells. Some fade, while others remain lifelong.

Congenital Melanocytic Nevi (Moles)

Moles appear at birth or early infancy. They may be flat or raised and range in color. Small ones rarely cause issues. Larger ones need monitoring due to a slightly higher risk of skin cancer. Use sun protection and check them regularly.

Café-au-lait Spots

These light brown patches are common and usually harmless. However, many spots or large ones with jagged borders may indicate a genetic condition. Your doctor may recommend tests.

Dermal Melanocytosis (Mongolian Spots)

Often seen in babies with darker skin, these blue-grey patches are common on the back or bottom. They usually fade by toddlerhood and don’t require treatment.

Pigmentary Mosaicism

These marks have swirling or streaky patterns. Color changes may appear later. While mostly harmless, large patches may need evaluation for related conditions.

When to Call Your Pediatrician

Some baby birthmarks and rashes may require medical attention. See your pediatrician if:

• The mark grows rapidly or changes color.
• There are many café-au-lait spots.
• Your baby has pain, swelling, or other symptoms.
• A birthmark affects vision, movement, or daily function.
