Nevus sebaceous of the eyelid: Unique presentation and literature review.

Nevus sebaceous has been described since 1895 by Jadassohn. It has been described as unctuous yellow nodules with granular-pitted surfaces as a hypertrophic sebaceous gland. It usually appears on the face, scalp, and neck. It has been stated to involve three stages. (1) Being small and yellow in nature and hairless. (2) Enlargement of the glandular part. (3) Malignant transformation. There are a few cases of nevus sebaceous involving the eyelid margin that have been reported in the English literature. We here report a case report of a nevus sebaceous in a child involving the upper and lower lid margin.
