4 main types: Most melanomas are called superficial spreading. Theyt tend to start by growing in the top planes of the skin and then go deeper. Nodular melanomas begin their vertical growth phase (burrowing deeper) earlier. Lentigo maligna are often on the face in the elderly and may be large. Acral lentiginous melanomas begin in fingers or toes and sometimes in the nonpigmented areas in dark-skinned people.
