Melanocytoma (magnocellular nevus) is a jet-black benign lesion histologically composed of polygonal tumor cells with small, inconspicuous nuclei and abundant cytoplasm. Melanocytomas in general are rare. Most cases occur in the optic nerve head. Conjunctival melanocytoma (magnocellular nevus) is extremely rare, and only 3 lesions of the ocular surface have been reported.
