Treatment of Divided Eyelid Nevus With Island Skin Flap: Report of Ten Cases and Review of the Literature

“…Grafts taken from behind the ear, the upper eyelid of the affected eye, the normal eye, or the upper arm, have been a successful procedure for white patients. 1,5,[11][12][13] For Asian patients, obvious hyperpigmentation, marked contracture, and poor texture of the grafts, even with full thickness skin grafts, often result in a permanent cosmetic or functional defect. With loss of subcutaneous fat, skin grafts may adhere to the levator aponeurosis, leading to ptosis.…”

“…2,15 Since malignant transformation in the intradermal portion of a compound nevus is extremely rare and no reported cases of divided nevi of the eyelids exist in the literature, 4,18,19 some authors prefer a partial excision to preserve the eyelid margin continuity and lacrimal drainage system. 1,20 The residual nevi are inconspicuous, and in female patients, it can be masked with make-up or tattoo, which is popular in Asia.…”

To the best of our knowledge, the association between common cavity, lipomeningocele and melanocytic naevus of the eyelid has never been described.…”
