Nevus sebaceus

A 35-year-old woman presented with cosmetically disturbing facial plaques, which had been present since birth and were consistent with nevus sebaceus on histopathologic examination. Nevus sebaceus is a congenital, hairless plaque, which is found most commonly on the scalp and face and typically becomes thicker and more verrucous in appearance as the patient enters adulthood. There is an association with benign and malignant neoplasms. Typically, these lesions are either removed surgically or the patients are followed clinically. Other therapeutic modalities utilized for cosmesis include carbon dioxide laser and photodynamic therapy.
