[Lentigo maligna treated with 5% imiquimod cream]. / Lentigo maligno tratado con crema de imiquimod al 5%

ABSTRACT

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. The treatment of choice for this pathology is surgical excision with margins of 0.5 cm. of clinically normal skin around the lesion, or Mohs microsurgery. 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.
