Managing lentigo maligna
Lentigo maligna (LM) most commonly presents in chronically sun-exposed areas in the middle-aged and elderly. Historically known by the eponym ‘Hutchinson’s melanocytic freckle’, LM presents as an often ill-defined, centrifugally expanding tan or dark brown area, usually on the face. With time, the lesion may acquire an invasive dermal component, and must then be reclassified as a lentigo maligna melanoma (LMM), which is estimated as representing some 15% of invasive melanomas.
