Lentigo maligna is also known as Hutchinson melanotic freckle. Lentigo maligna occurs in sun-damaged skin so is generally found on the bald scalp, face or neck, particularly the nose and cheek of older adults Lentigo maligna (LM) is the most common subtype of in situ melanoma und occurs frequently in the sun-exposed head and neck region in elderly patients.

However, surgery is not feasible in certain patients due to age, comorbidities or patient preference
