Slow-growing variant of melanoma arising in a premalignant lesion, lentigo maligna, which appears on the sun-exposed skin of elderly people. It has a long preinvasive period. Initially the lentigo maligna is a flat, brown, stain-like lesion. The development of an elevated nodule within the area of pigmentation indicates the change to vertically invasive lentigo maligna melanoma. This variant does not occur in children.
