Histologic examination of the lesion showed numerous villous papillary projections extending into the lumina of cystic invaginations, which were connected to a papillomatous epidermis. A collection of mature sebaceous glands and ectopic apocrine glands was also noted.

Nevus sebaceus, which is a circumscribed hamartoma predominantly composed of sebaceous glands, occurs mainly on the face and scalp.1 The lesion may be round, oval, or linear and of variable length. Although SN and verrucous epidermal nevi are considered to be variants of the same disorder, some authors recommend prophylactic surgery in cases of SN because of the potential risk of malignancy.2
