Lentigo maligna (LM) is considered to be an in-situ stage of lentigo maligna melanoma. Clinically, it presents as a pigmented macule, irregular in shape and tone. 30% to 35% of untreated lentigo malignas can progress into lentigo maligna melanoma. ⋯ Imiquimod is a topical immunomodulator that stimulates both acquired and innate immunity. We present the case of a patient with LM, treated with 5% imiquimod cream, with an excellent therapeutic response.
