This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the Editors because the photograph in Figure 1b was a duplicate image of Figure 1a, but with the keratosis removed, and did not represent the surgery that was described in the article. The authors apologise for this error. Crown
