Mohs Surgery for Periungual

28

and Subungual Skin Cancer

Steven Chow and Richard G. Bennett

Abstract

Mohs surgery for a malignancy in the periungual and subungual location is advantageous because it is a tissue-sparing technique that preserves maximum function and normal appearance. Traditional surgical treatment for such tumors is wide local excision and closure; in some cases, amputation of the digit is considered. The amount of tissue removed with these standard surgical treatments may be quite debilitating for the patient. Often, Mohs surgery will preserve a significant amount of nail matrix so that an almost normal-appearing nail regrows.

Mohs surgery for a malignancy in the periungual and subungual location is advantageous because it is a tis- sue-sparing technique that preserves maximum function and normal appearance. Traditional surgical treatment for such tumors is wide local excision and closure; in some cases, amputation of the digit is considered. The amount of tissue removed with these standard surgical treatments may be quite debilitating for the patient. Often, Mohs surgery will preserve a significant amount of nail matrix so that an almost nor- mal-appearing nail regrows.
