Thank you very much for apprising us of the reader’s interest in our article.1 We respect the opinion. The incidence of malignant melanoma arising from small/medium congenital melanocytic nevi is an important issue. Although most of them are assessed to be safe, malignant melanoma actually develops in such nevi. It is practically impossible to conduct lifetime follow-up to identify the malignant transformation of these nevi, because the congenital melanocytic nevi appear in babies and ordinary malignant melanoma usually develops in the sixth to eighth decades. Therefore, in our study, we established a certain period and checked the incidence of congenital melanocytic nevi and malignant melanoma arising from small/medium congenital melanocytic nevi who visited our hospital.1 Based on our study, we need to pay attention to possible underestimation of the risk of malignant transformation of such lesions.1 We agree with the prophylactic surgical excision of the lesions. The surgical factors related to patients are well analyzed in the article. If further research on the factors related to lesion, for example, regarding which lesions should be removed by surgery, is carried out, it will be welcome.
