Mohs Micrographic Surgery at Challenging Anatomical Sites

Abstract

Background: Mohs micrographic surgery (MMS) is often the treatment of choice for skin cancer removal as it maximizes normal tissue sparing and can be paired with a reconstructive approach that optimizes function and cosmesis. Many tumors on the eyelid, nose, ear, and genitals are particularly well suited for MMS but can be challenging for the dermatologic surgeon.

Objective: To review the complex anatomy, as well as the authors' approach to executing and interpreting Mohs layers, at each of these anatomical sites.

Methods: A review of the literature on MMS of the eyelid, nose, ear, and genitals was performed using the PubMed database and relevant search terms.

Conclusion: These sites present potential pitfalls for tumor resection and reconstruction, but with the proper technique, the dermatologic surgeon can minimize tumor recurrence and MMS complications. Warning signs for potentially difficult tumor resection can signify when an interdisciplinary approach is warranted.
