Special considerations for Mohs micrographic surgery on the eyelids, lips, genitalia, and nail unit

Although skin cancers on the eyelids, lips, genitalia, and the nail unit are infrequent, some skin cancers can have higher recurrence rates in these anatomic locations. Intrinsic to Mohs micrographic surgery (MMS) is maximal tissue preservation and high cure rates, making it a worthwhile procedure for these sensitive anatomic areas to ameliorate any functional or aesthetic compromise. The Mohs surgeon can provide a great service to patients by being aware of the anatomy, specialized instruments, unique histology, and potential complications when performing MMS on these areas.
