title: The pigmented portio: benign lentigo of the uterine cervix.
abstract: The first case of benign lentigo of the uterine cervix  is reported, providing further evidence that the cervix is able to form the entire spectrum of melanocytic lesions known to occur in the skin. Review of the literature reveals 19 cases of primary malignant melanoma of the cervix and 30 cases of blue nevus. The reported case offers support that benign lentigines may play a role as premalignant lesions of malignant melanoma not only in the skin, but aldo in mucous membranes.
