Amelanotic lentigo maligna melanoma of the face: a case report and review of the literature.

Amelanotic lentigo maligna melanoma is rare, only 10 cases over the face having been reported to date in the English literature. In none of these was the diagnosis suspected clinically, being made in all cases only after histopathological examination. We now report an unusual additional case of this uncommon lesion, which quickly progressed from an amelanotic lentigo maligna to an invasive melanoma in a short space of time, and review the literature concerning this condition.
