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 or through one-year Mohs surgery fellowship training programs administered by the American College of Mohs Surgery. 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. 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. Pediatric dermatology Physicians can qualify for this specialization by completing both a pediatric residency and a dermatology residency. Or they might elect to complete a post-residency fellowship. This field encompasses the complex diseases of the neonates, hereditary skin diseases or genodermatoses, and the many difficulties of working with the pediatric population. Teledermatology Teledermatology is a form of dermatological practice in which telecommunication technologies are used to exchange medical information and treatment through audio, visual, and data communication, including photos of dermatologic conditions, between dermatologists and nondermatologists who are evaluating patients, along with dermatologists directly with patients via distance. In India, during the severe coronavirus situations, some dermatologists have initiated online consultation with their patients using some of popular apps, such as Practo, Apollo Pharmacy, Skin Beauty Pal, Lybrate, etc. This subspecialty deals with options to view skin conditions over a large distance to provide knowledge exchange, to establish second-opinion services for experts, or to use this for follow-up of individuals with chronic skin conditions. Teledermatology can reduce wait times by allowing dermatologists to treat minor conditions online while serious conditions requiring immediate care are given priority for appointments. Dermatoepidemiology Dermatoepidemiology is the study of skin disease at the population level. One of its aspects is the determination of the global burden of skin diseases. From 1990 to 2013, skin disease
