Pigmented Birthmarks

Pigmented birthmarks are areas of skin that appear darker than the surrounding tissue due to increased melanin. Common types include café-au-lait macules, congenital melanocytic naevi, and speckled lentiginous naevi. They may be present at birth or appear in early infancy.

Some do. Congenital naevi typically enlarge as a child grows (proportionate growth). Colour may darken with age or sun exposure. Any rapid change in size, colour, itching, bleeding or asymmetry warrants urgent dermatology review.

‍

Most pigmented birthmarks are completely harmless. However, larger congenital melanocytic naevi carry a small but real lifetime risk of melanoma. Dermatologists assess features such as size, colour change, borders, hair growth and texture to determine risk.

Yes, many can be lightened or removed depending on the type. Options include:

• Pigment lasers (Picosecond, Q-Switch, Excel V+)

• Surgical excision (for raised or high-risk lesions)

• Observation only (if cosmetic risk outweighs benefit)Your clinician will determine feasibility — not all birthmarks respond fully to lasers.

Seek assessment if:
• The birthmark is large or growing
• It has irregular borders or uneven colour
• It has changed recently
• It is located in a cosmetically sensitive area
• You want advice on treatment options for appearance or safety
