It has been said that CO 2 laser vaporization and resection conventionally performed for elevated lentigo may cause depressed scar formation when the diameter of the lesion exceeds 5 mm. Accordingly, in consideration of cosmetic factors, we have devised a method for the removal of even a larger elevated lentigo by the Flat Resection technique which can be used effectively without causing a depressed scar to form. Upon the primary laser irradiation, the lesion was resected at the horizontal plane of the skin, and the resected tumor was subjected to histopathological analysis. If the lesion remained about one month after the primary irradiation, additional laser treatment was performed at the patient's request. From our experience, satisfactory outcomes were obtained for up to 12‐mm lesions. Following the flat resection, residual lesions were pathologically observed in 52.5%, and macroscopically observed in 45%. Additional laser treatment was performed for 35%. It was considered that this technique is useful for sites such as the base of ala nasi and the vicinity of the eyebrow, of which simple reefing requires skills. However, since the possibility of malignant degeneration of lentigo could not be ruled out in a longer‐term follow‐up, particular care is needed to select a case suitable for this technique.
