Lentigo maligna melanoma is a type of invasive skin cancer. It develops from lentigo maligna, which is sometimes called Hutchinson’s melanotic freckle. Lentigo maligna stays on the outer surface of the skin. When it starts growing beneath the skin’s surface, it becomes lentigo maligna melanoma.
What stage is lentigo maligna melanoma?
|Stage 0||In situ melanoma including lentigo maligna|
