title: [Malignant lentigo melanoma].
abstract: Malignant melanoma (MM) arises either from a pre-existing, pigmented nevus, from clinically normal skin, or in rare cases from the non-nevoid lesion named lentigo maligna (LM). We present two cases of LM, one in a 75-year old woman and one in an 89-year old woman, which progressed to MM over ten and two years respectively.
