What are Birthmarks?
Birthmarks are congenital (present at birth or appearing shortly after) skin markings caused by overgrowth of blood vessels, melanocytes, or other skin cells. They can be classified into:
- Vascular Birthmarks (caused by blood vessels)
- Port-wine stains (reddish-purple patches)
- Hemangiomas (raised red or purple growths)
- Salmon patches (light pink or red marks, often on the eyelids or neck)
- Pigmented Birthmarks (caused by excess pigment)
- Moles (Congenital Nevi) (brown, tan, or black spots)
- Café-au-lait spots (light brown, oval-shaped patches)
- Mongolian spots (blue-grey patches, common in darker skin tones)
Management & Treatment Options for Birthmarks
Observation & Monitoring
- Many birthmarks do not require treatment and fade over time (e.g., salmon patches, hemangiomas).
- If a birthmark changes in shape, size, or color, a doctor should evaluate it.
Medical & Cosmetic Treatments
Pigmented Birthmarks
- Café-au-lait spots: Usually harmless; laser therapy can lighten them.
- Congenital moles:
- Small moles are generally benign but should be monitored for changes.
- Large congenital moles have a higher risk of melanoma and may require surgical removal.
- Mongolian spots: Common in darker skin tones, usually fade naturally in childhood.
Vascular Birthmarks
- Salmon patches (stork bites, angel kisses): Usually fade without treatment.
- Hemangiomas:
- Most shrink naturally; for large or problematic ones, a class of drugs called beta-blockers (oral propranolol or topical timolol) can be used.
- Laser therapy or corticosteroids may be used if they cause complications.
- Port-wine stains:
- Do not fade on their own; may darken over time.
- Laser therapy (pulsed dye laser) can significantly lighten or remove stains, making them less visible.
- In some cases, makeup (e.g., Dermablend) can help conceal discoloration.
