The conjunctiva is a diaphanous mucous membrane that covers the anterior surface of the eye and lines the inner surface of the eyelids. The conjunctival epithelium of the semilunar plica (crescentic fold located in the medial interpalpebral angle of the eye, a presumed remnant of the nictitating membrane) minimally differs from the anterior surface conjunctiva in that it possesses a more prominent population of goblet cells. The conjunctival epithelium contains dendritic melanocytes in the basal layers and may contain nevus cells of the common, epithelioid, and fusiform types. Thus, the conjunctiva is the seat of a wide spectrum of benign and malignant pigmented lesions equivalent to those affecting the skin, including balloon cell nevi, Spitz nevi, blue and cellular nevi, combined nevi, and malignant melanoma.1- 2 With only minor modifications adapted to the microscopic anatomy, the nomenclature applied to conjunctival nevi is comparable to that used for the skin. In descending order, the most common locations for benign conjunctival nevi are juxtalimbal, epibulbar, the plica, the caruncle, and the eyelid margin.
