Early- and mid-career Mohs surgeons appear to remove tumors with similar numbers of stages regardless of their experience, case volume, or geographic location. Number of stages varies with anatomic location and tumor type. The authors have indicated no significant interest with commercial supporters.

Pseudo-ainhum is an auto-amputation of the digits. Although extremely rare, it is a traumatic and painful experience that can be alleviated with early recognition and intervention. The scientific literature is filled with reports of this interesting but unfortunate phenomenon. To date, a firm causative aetiology has not yet been established. Although reports on this phenomenon have attempted to further our understanding of pseudo-ainhum, a clear understanding has been complicated by the interchangeable use of terms describing this auto-amputation. In this review, we discuss the current understanding, diagnostic criteria, and management of pseudo-ainhum. Furthermore, the nomenclature of pseudo-ainhum is clarified. Ideally, this will allow for more efficient exploration of pseudo-ainhum, its causes, and therapeutic approaches.

High-ranking websites provide basic information about MMS. Academic practice and professional society sites provide more-comprehensive information, but private practice sites and web-based medical information sources also provide additional information.

Cochrane reviews offer outstandingly complete evidence-based summaries of their topics. As such, the methodology of Cochrane reviews is a model for reviews in dermatologic surgery. Because of the dearth of high-level evidence in dermatologic surgery, the ability of Cochrane reviews to provide specific recommendations remains limited. Furthermore, dermatologic surgery may be inherently difficult to study because of the rapid evolution of procedures, intraprocedure complexity and variation, difficulties inherent in randomizing patients to interventions, and intersurgeon skill variation. That being said, the dermatologic surgery literature continues to improve and grow, and investigators are now broaching the special challenges associated with research in this area.
