title: Macular amelanotic melanoma in situ.
abstract: This report aims at directing the attention to the rare entity of amelanotic melanoma in situ, as exemplified in a patient who had an amelanotic lentigo maligna 10 years ago and a recurrent lesion of identical clinical and histological (except for pagetoid tumor cells in the epidermis) appearance 4 years ago. Amelanotic melanomas in situ appear as inconspicuous reddish macules, which can hardly be diagnosed or even suspected on clinical grounds.
