Pigmented Birthmarks
Skin discolouration resulting from clusters of pigmentation cells (melanocytes) appearing as tan, brown, black or blue spots/patches.
Pigmented birthmarks are skin markings that are either present at birth or appear within the first few weeks of life. They result from an overproduction of melanin or a clustering of pigment-producing cells (melanocytes) in the skin.
The Science Behind It
What are the most common pigmented birthmarks?
- Café-au-Lait Spots: Light brown patches that vary in size, shape, and number. While common and usually harmless, having six or more spots larger than 0.5 cm in children may be linked to a genetic condition such as neurofibromatosis and should be assessed by a doctor.
- Mongolian Spots: Flat, bluish-grey birthmarks most often seen on the lower back or buttocks. They are more common in babies with darker skin tones and are caused by pigment cells trapped in the deeper layers of the skin. These marks usually fade by early childhood and do not require treatment.
- Congenital Nevi: Moles present at birth that can appear anywhere on the body. They may be flat or raised and range in colour from brown to black. Larger nevi may carry a slightly increased risk of developing into melanoma later in life, so regular monitoring is recommended.
