Introduction
Mohs micrographic surgery, which is performed in the office using local anesthesia, is a state-of-the-art treatment for skin cancer in which the physician serves as a surgeon, pathologist, and reconstructive surgeon. It yields the highest cure rate of all skin cancer treatments, with cure rates approaching 99% for tumors that have not previously been treated. The procedure relies on the precision and accuracy of examining tissue under a microscope to trace and ensure removal of the skin cancer, which may have roots that extend beyond what is visible to the naked eye. In addition, the removal of healthy skin is minimized, resulting in the smallest possible surgical defect and thereby decreasing the potential for scarring.
