Superficial spreading melanoma: The most common type; lesions are usually flat, irregular in shape, and contain varying shades of black and brown. It can occur at any age.
Lentigo maligna melanoma: Usually affects the elderly; involves large, flat, brownish lesions
Nodular melanoma: Can be dark blue, black, orreddish-blue, but may have no color at all. It usually starts as a raised patch.
Acral lentiginous melanoma: The least common type; typically affects the palms, soles of the feet, or under finger and toenails (AAD, 2010).
