Traditional surgical treatment of nonmelanoma skin cancer includes excision with subsequent evaluation of surgical margins, either via frozen sections intraoperatively or after excision and closure. Accurate communication between surgeon and pathologist regarding the meaning of surgical margins should be confirmed. Recurrences of tumor growth may in part be attributed to asymmetrical tumor growth patterns with extension of tumor in an unanticipated direction. Mohs micrographic surgery is an outpatient procedure that maximizes surgical margin evaluation while minimizing the amount of tissue that must be excised. This article will discuss the concept of surgical margins in excisions of nonmelanoma skin cancer and the role of Mohs micrographic surgery.

Two conflicting hypotheses have been tested concerning the association between a personal history of nonmelanoma skin cancer (NMSC) and risk of other malignancies. One hypothesis is that as a marker of extensive sunlight exposure and hence vitamin D status, NMSC should be inversely associated with risk of other cancers. Alternatively, under the multiple primary cancer model, NMSC is postulated to be an informative first cancer to study as a marker of increased risk of subsequent primary cancer diagnoses. In this journal issue, Ong and colleagues report the results of a large-scale study in the United Kingdom with findings that NMSC was significantly associated with increased risk of a broad spectrum of other malignancies, with the associations stronger the younger the age of onset of NMSC. These results are consistent with the larger body of evidence on this topic, which is highly asymmetrical in favor of the multiple primary cancer hypothesis. Two divergent hypotheses have been tested, with the empirical evidence unequivocally indicating that NMSC is a marker of a high cancer risk phenotype. Future research is warranted to better characterize this association, to understand why NMSC is a marker of excess risk of other cancers, and to determine whether this association is clinically relevant.
