• Nodular melanoma: shiny, firm, dome-shaped brown, black or pink bumps anywhere on skin
• Acral lentiginous melanoma: irregular brown to black flat lesions on palms, soles, tips of fingers or toes, or mucous membranes; can also be a brown or black streak under a finger or toenail
• Lentigo maligna melanoma: large brownish irregular spot with darker speckles on skin overexposed to sun, particularly the face or arms
