“Dermohscopy” mapping: Correlating dermoscopic findings with histology in Mohs micrographic surgery

Mapping is an essential step during Mohs micrographic surgery (MMS) since it allows tumors seen on histology to be tracked during surgery. Histologic findings are typically correlated to the clinical photo or to the hand-drawn map. Despite the increasing use of dermoscopy as an adjuvant tool to help identify basal cell carcinoma, mapping the dermoscopic findings before MMS has not been described to the author's knowledge. The author describes the "dermohscopy" mapping to better correlate dermoscopic findings with histology in MMS.
