Is Your Birthmark Hiding a Secret?

Dec 17
2025

When it comes to birthmarks, many people wonder what they are and if they could potentially hide a secret about their health. Birthmarks are quite common and, in most cases, harmless. They are typically benign skin lesions that come in various shapes and sizes, and many will fade or disappear entirely over time.

However, while the majority of birthmarks are nothing to worry about, some variants can indicate underlying health concerns.

Can a Birthmark Be Dangerous?

Understanding the complexities of birthmarks starts with recognizing that they are mainly categorized into two types: vascular and pigmented.

1. Vascular birthmarks, like port-wine stains or hemangiomas, result from abnormal blood vessels in the skin.
2. Pigmented birthmarks, such as moles and congenital melanocytic nevi, are comprised of an excess of pigment-producing cells.

The latter type warrants more caution, particularly if they present certain characteristics.

The Risks of Large Congenital Melanocytic Nevi

Large congenital melanocytic nevi (CMN), which are moles present at birth, have a heightened risk of developing into melanoma, a serious form of skin cancer. The risk is particularly significant when these nevi are sizable or if they undergo changes in size, shape or color. Any change in these characteristics should prompt a consultation with a birthmark specialist. Regular monitoring is crucial, and early intervention can lead to more favorable outcomes.

Certain Port-Wine-Stains

While some birthmarks are merely cosmetic, others may be a sign of deeper health issues. For instance, a port-wine stain that appears on the forehead or eyelid should not be overlooked. If it is accompanied by several cafe-au-lait spots, it could potentially suggest Sturge-Weber syndrome, a rare neurological condition that affects the brain and eyes. Awareness of these signs can be instrumental in ensuring a timely diagnosis and appropriate treatment.
