Two patients presented with the unusual occurrence of isolated foci of malignant melanoma of the upper eyelid and ipsilateral inferior conjunctiva. Neither patient had clinical evidence of primary acquired conjunctival melanosis, but in one case there was histopathologic evidence of this condition. The clinical features, histopathologic findings, and possible significance of this unusual occurrence are discussed.
