Melanoma of the face

Abstract

Lentigo maligna and lentigo maligna melanoma represent a characteristic, histogenetic subclass of melanocytic malignancies. They are found on chronically light-exposed skin, usually the face of middle-aged and elderly people. During the long preinvasive period, called lentigo maligna, a very slow horizontal growth can be observed. After a variable period of time, invasion into the underlying dermis will occur. Other names for the preceding horizontal or in-situ growth phase are Hutchinson's melanotic freckle and premalignant melanosis of Dubreuilh. Once obvious dermal invasion is present, the name lentigo maligna melanoma is appropriate. © 2007 Springer-Verlag.
