Abstract

A 20-year-old girl presented with a large pigmented lesion over the temporal aspect of left lateral canthus involving the lateral one-third of both eyelids, since birth. A slow increase in its size had been noticed for the past 2 years. On examination, a hairy nevus measuring 34 mm × 22 mm was noticed involving left eyelid skin, the mucocutaneous junction (MCJ), palpebral conjunctiva, and lateral canthus. The surface was irregularly thick and covered with long, thick, and pigmented hairs. A clinical diagnosis of kissing nevus of eyelids was kept and a surgical resection with reconstruction planned. A customized full-thickness skin graft (FTSG) and amniotic membrane grafts (AMGs) were used for the reconstruction of cutaneous and MCJ, respectively. Histopathology showed the features of junctional nevus. At 4 months of follow-up, a well taken FTSG and healthy/sharp MCJ were noticed with no recurrence. We advocate a possible role of AMG, particularly in the reconstruction of the conjunctival mucosa and MCJ.
