Lentigo maligna is a subtype of melanoma that may progress to Lentigo maligna melanoma as it becomes invasive. Age and sun exposure are risk factors. Excisional surgery and Mohs micrographic surgery are the traditional choices of treatment. Grenz rays may be a reasonable therapy. Cryosurgery appears to be a valid option as melanocytes are particularly susceptible to be destroyed by low temperatures; a combination of this method plus imiquimod has been reported as successful.
