Lentigo maligna is an in situ melanoma which usually affects sun-damaged skin on the head and neck. In patients with lentigo maligna, the clinically visible demarcation often correlates poorly with the histopathologically confirmed demarcation. Micrograhic surgery of lentigo maligna offers certainty of the presence of clear histological margins and is at the same time tissue sparing. Because of the clear margins after micrographic surgery, this technique leads to fewer recurrences than standard excision.
