Nevus sebaceous

Nevus sebaceous

A lesion that can be found on an infant’s scalp or neck, varies in size (usually a few centimeters), well defined, round or striped, mostly yellowish or orange colored (See photo), accompanied by hairlessness.
The lesion stays flat until adolescence and then grows and thickness as a result of the glands in its underlying tissue.
In most cases it presents as a single lesion without any additional findings.

What are the problems associated with nevus sebaceous?

Firstly, cosmetic. The area appearing hairless contrasting with the rest of the scalp. The area expands after adolescence.
The second problem is rare and more complex. At older age (long after adolescence) there is an increased chance of malignant transformation in these lesions (14% up to the age of 120 years).
Therefore, the solution is removing the nevus.

When is the right time for the lesion to be removed and by whom?

Removal of a lesion is usually carried out during adolescence by a pediatric plastic surgeon. Usually after the age of 12 years (various between different medical institutes). Lesions that are not large can be removed under local anesthesia and this is an advantage.
There is an alternative opinion that claims a better outcome if removal is performed during infancy where there is a bit more scalp tissue.
So, I recommend you consult a pediatric dermatologist and a plastic surgeon to discuss the removal of the lesion.
And most important – do not worry at all.
