Mohs Micrographic Surgery: A Brief Overview

Mohs micrographic surgery (MMS) is a tissue-sparing skin cancer resection technique that involves 100% margin analysis. This procedure is performed in the outpatient setting under local anesthesia by dermatologic surgeons who act as both the surgeon and the pathologist. The technique allows for prompt reconstruction immediately after cancer clearance and offers the highest cure rate for many skin malignancies, including basal and squamous cell carcinoma, as well as more rare tumors. Mohs surgery effectively ensures cancer clearance while minimizing defect size and optimizing cosmetic and functional outcomes for patients. Herein we will discuss the evolution, procedure, and indications of MMS.
