[Diagnostics and treatment of lentigo maligna melanoma in Denmark].

The incidence of maligna melanoma has doubled in Denmark over the latest 30 years. Lentigo maligna melanomas (LMM) account for 10-26% of the melanomas in head and neck. LMM most often strike people over the age of 70 years and frequently occur in sun-exposed skin areas. LMM can be difficult to diagnose, since its clinical features are similar to benign skin lesions, solar lentigo and seborrhoeic keratosis. This review presents various methods for diagnosing and treating LMM. The specific method is chosen in dialogue with the patients, and overall health is an important factor when choosing an appropriate treatment.
