Een neonaat met een huidafwijking op de scalp

A term-born boy presented with a solitary, oval, hairless plaque on the scalp. The skin lesion was red-yellow coloured and had a waxy aspect. The diagnosis ‘nevus sebaceous’ was established, a hamartoma with a combination of abnormalities of the epidermis, hair follicles and sebaceous and apocrine glands. Prophylactic excision of these lesions is controversial because of the low incidence of progression to malignancy.
