Lentigo maligna melanoma is a subtype of melanoma that develops when a lentigo maligna (a subtype of melanoma in situ) enters vertical growth phase and invades into the dermis. It is a tumor that may grow slightly above the surface of the skin and may be prone to bleeding. This cancer generally occurs 5-20 years after the lentigo maligna first develops. It is most frequently seen on sun-damaged skin (usually on the face) in individuals aged 60 or older.
Lentigo maligna melanoma is associated with nonmelanoma skin cancers, light skin, Werner syndrome, oculocutaneous albinism, and xeroderma pigmentosa.
