Can a person develop multiple lentigo maligna melanoma in different parts of the body?

Yes.  Up to 8% of all individuals with some type of melanoma go on to develop a second melanoma.  Lentigo maligna melanoma has been found to be a risk factor for developing a second melanoma, typically in a part of the body that has a history of significant sun exposure.[1]

Is lentigo maligna melanoma genetic?

Lentigo maligna melanoma (LMM) is not believed to be inherited (arising from a genetic predisposition).  LMM is thought to be caused by a history of significant sun exposure.[2]
