L entigo maligna (LM) is an in situ lesion with a 2% to 50% risk of progression to LM melanoma. 1 Currently, surgery or radiotherapy is usually recommended as the primary treatment for LM. In the literature, the recurrence rates reported for radiotherapy range from 0% to 19%, with a mean recurrence rate of approximately 7%; in addition, radiotherapy carries the risk of causing chronic radiodermatitis or radiation-induced malignant neoplasm. 2 A margincontrolled excision using "slow Mohs" (rush permanent sections) and Mohs micrographic surgery has the lowest recurrence rate, perhaps as low as 3%. 3Methods. Thirty-two patients with 34 histologically confirmed facial LM lesions were enrolled in an open-label trial of imiquimod, 5%, cream (Aldara; 3M Pharma, Rueschlikon, Switzerland). No patient had been treated
