A 29-year-old woman presented with dark-colored raised lesions on both eyelids since early childhood. Ophthalmological examination revealed pigmented verrucous lesions on her upper and lower eyelids bilaterally. The patient had a history of generalized tonic-clonic seizures. Dermatological examination revealed hyperpigmented verrucous plaques arranged along lines of Blaschko on the neck, trunk, and arms. On the basis of these findings, the diagnosis of epidermal nevus syndrome (ENS) was made.

... e had surgery for debulking of the lesions. Histological analysis revealed hyperkeratosis with foci of parakeratosis, acanthosis, and papillomatosis, consistent with linear verrucous epidermal nevus. Postoperative residual lesions did not respond to oral acitretin therapy (10 mg/kg/day for 2 months). Systematized ENS can rarely cause linear verrucous nevi on the upper and lower eyelids on both sides. These patients should be investigated for accompanying systemic anomalies and followed for potential malignant transformation of the skin lesions.
