Lentigo Maligna

definition

Slowly growing premalignant disease due to proliferation of atypical melanocytes within the epidermis, which can progress to lentigo maligna melanoma. Patients are usually in their sixth or seventh decade. The typical lesion is a brown-black macula arising on chronically sun-exposed parts of the body, mainly on the face. Usually, the margin is indefinite. Changes to deep-black colour and elevation or slight infiltration suggest lentigo maligna melanoma.
