===Mohs surgery===
{{Main|Mohs surgery}}
The dermatologic subspecialty called Mohs surgery focuses on the excision of skin cancers using a technique that allows intraoperative assessment of most of the peripheral and deep tumor margins. Developed in the 1930s by [[Frederic E. Mohs]], the procedure is defined as a type of [[CCPDMA]] processing. Physicians trained in this technique must be comfortable with both pathology and surgery, and dermatologists receive extensive training in both during their residency. Physicians who perform Mohs surgery can receive training in this specialized technique during their dermatology residency, but many seek additional training either through formal preceptorships to become fellows of the American Society for Mohs Surgery<ref>{{cite web| title=About ASMS|publisher=American Society for Mohs Surgery| url=http://www.mohssurgery.org/about-asms/}}</ref> or through one-year Mohs surgery fellowship training programs administered by the American College of Mohs Surgery.<ref>{{cite web |url=http://www.mohscollege.org/acms/difference.php |title=The Mohs College Difference |publisher=Mohscollege.org |access-date=2012-10-28 |archive-date=2011-05-12 |archive-url=https://web.archive.org/web/20110512214738/http://www.mohscollege.org/acms/difference.php |url-status=dead }}</ref> In 2020, the American Board of Dermatology (ABD) received approval from the American Board of Medical Specialties (ABMS) to establish a board-certification exam in the subspecialty of Micrographic Dermatologic Surgery (Mohs Surgery). The exam was first offered in October 2021 to any US board-certified dermatologist who practices Mohs surgery, regardless of whether they received their training in dermatology residency or as part of a fellowship.<ref>{{cite web |url=https://www.abderm.org/public/announcements/mds-subspecialty-certification-exam-study-guide-and-faqs.aspx |title=MDS Exam |publisher=abderm.org |access-date=2021-10-30 |archive-date=2021-12-02 |archive-url=https://web.archive.org/web/20211202210214/https://www.abderm.org/public/announcements/mds-subspecialty-certification-exam-study-guide-and-faqs.aspx |url-status=dead }}</ref>

This technique requires the integration of the same doctor in two different capacities - surgeon and pathologist. In case either of the two responsibilities is assigned to another doctor or qualified health-care professional, it is not considered to be Mohs surgery.{{cn|date=April 2021}}
