Lentigo maligna is a type of growth that develops in areas of long-term sun exposure, such as your face, arms or legs. Lentigo maligna starts as a brown flat spot with an irregular shape that slowly gets bigger. Eventually the spot may develop into melanoma, a type of skin cancer that begins in the top layer of skin and then invades the underlying skin layer. See your doctor if you notice:

  • A new skin growth
  • A change in an existing mole
  • Any skin changes that seems unusual
