Generally, birthmarks are neither good nor bad; most are harmless skin markings that are permanent. Here's a more detailed breakdown:
Most birthmarks are harmless but permanent. The only ones that fade with time are Mongolian spots and haemangiomas of infancy.
Understanding Birthmarks
Birthmarks are common skin discolorations that are present at birth or develop shortly after. They come in various forms and can differ significantly in appearance.
Types of Birthmarks
| Type | Description | Fading Potential | Potential Issues |
|---|---|---|---|
| Mongolian Spots | Blue or gray colored spots, usually on the lower back or buttocks. | Yes | None |
| Haemangiomas of Infancy | Red, raised marks (also known as strawberry marks) | Yes | Can grow over the eye, block a nostril, ulcerate, or cause other problems needing treatment. |
| Other Birthmarks | Other types can range from flat to raised marks and can vary in color (e.g., cafe-au-lait spots, port-wine stains, congenital nevi (moles). | No | While most are benign, some may have a slight increased risk of developing melanoma (in case of larger congenital nevi). |
It is vital to consult a healthcare professional for diagnosis, especially in the case of problematic birthmarks like haemangiomas.
When Birthmarks May Be a Concern
- Growth or Changes: If a birthmark rapidly grows in size, changes color, or becomes raised, consult a doctor.
- Location: Some birthmarks, such as haemangiomas near the eyes or nostrils, can cause complications, as mentioned in the reference.
- Ulceration: If a birthmark becomes ulcerated or painful, it needs medical attention.
The reference notes that haemangiomas of infancy may occasionally need treatment, indicating that some birthmarks can cause issues.
Key Takeaways
- Most birthmarks are harmless: They are a natural part of development.
- Some fade over time: Mongolian spots and haemangiomas of infancy often disappear.
- Others are permanent: Most birthmarks do not fade and are permanent.
- Treatment may be needed: In certain cases, such as with problem haemangiomas, treatment may be required.
