Blue nevus of the tarsus as the predominant component of a combined nevus of the eyelid

Ophthalmic Plast Reconstr Surg. 2011 Jul-Aug;27(4):e94-6. doi: 10.1097/IOP.0b013e3181f0b6d5.

Abstract

A 40-year-old man presented with a pigmented lesion of the palpebral conjunctiva and margin of the right lower eyelid. Because of suspicion of melanoma, the lesion was resected. Microscopic examination revealed 2 distinct components: a dominant blue nevus in the tarsus consisting of bland pigmented spindle and epithelioid cells that dissected among the orbicularis muscle fibers and meibomian glands, and a small subepithelial nevomelanocytic component with no overlying junctional activity. The diagnosis of a combined nevus was supported by minimal Ki-67 nuclear immunoreactivity. While the current lesion was proved to be an atypical nevus, all palpebral pigmented lesions should be routinely excised because many are melanomas.
