The surgical approach to lentigo maligna is a challenge to dermatologists, given the difficulty of clinical delimitation of borders. We report here a case of a 69-year-old female patient presenting with brownish macules on her face, since 10 years ago, with histopathological diagnosis of lentigo maligna. The surgical management employed was excision of visible borders with the contoured technique and immediate submission of these borders for histopathological analysis before complete excision of the tumor. This technique is a variant of staged excision, with lower rates of recurrence and acceptable aesthetic results.
