Dermatology

Dermatology is the branch of medicine dealing with the hair, nails, skin and its diseases. It is a specialty with both medical and surgical aspects. A dermatologist treats diseases, in the widest sense, and some cosmetic problems of the skin, scalp, hair, and nails.

Etymology

Attested in English in 1819, the word dermatology derives from the Greek δέρματος (dermatos), genitive of δέρμα (derma), "skin" (itself from δέρω dero, "to flay") and -λογία -logia,

History

Readily visible alterations of the skin surface have been recognized since the dawn of history, with some being treated, and some not. In 1801 the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, while the first textbooks (Willan's, 1798–1808) and atlases (Alibert's, 1806–1814) appeared in print during the same period of time.

Training



United States

After earning a medical degree (M.D. or D.O.), the length of training in the United States for a general dermatologist to be eligible for Board Certification by the American Academy of Dermatology, American Board of Dermatology or the American Osteopathic Board of Dermatology is a total of four years. This training consists of an initial medical, transitional, or surgical intern year followed by a three-year dermatology residency. Following this training, one- or two- year post-residency fellowships are available in immunodermatology, phototherapy, laser medicine, Mohs micrographic surgery, cosmetic surgery or dermatopathology. For the past several years, dermatology residency positions in the United States have been one of the most competitive to obtain.

Fellowships



Cosmetic dermatology

Dermatologists have been leaders in the field of cosmetic surgery. Some dermatologists complete fellowships in surgical dermatology. Many are trained in their residency on the use of botox, fillers, and laser surgery. Some dermatologists perform cosmetic procedures including liposuction, blepharoplasty, and face lifts. Most dermatologists limit their cosmetic practice to minimally invasive procedures. Despite an absence of formal guidelines from the American Board of Dermatology, many cosmetic fellowships are offered in both surgery and laser medicine.

Dermatopathology

A dermatolopathologist is a pathologist or dermatologist who specializes in the pathology of the skin. This field is shared by dermatologists and pathologists. Usually a dermatologist or pathologist will complete one year of dermatopathology fellowship. This usually includes six months of general pathology, and six months of dermatopathology. Alumni of both specialties can qualify as dermatopathologists. At the completion of a standard residency in dermatology, many dermatologists are also competent at dermatopathology. Some dermatopathologists qualify to sit for their examinations by completing a residency in dermatology and one in pathology.

Immunodermatology

This field specializes in the treatment of immune-mediated skin diseases such as lupus, bullous pemphigoid, pemphigus vulgaris, and other immune-mediated skin disorders. Specialists in this field often run their own immunopathology labs.

Mohs surgery

The dermatologic subspecialty called Mohs surgery focuses on the excision of skin cancers using a tissue-sparing technique that allows intraoperative assessment of 100% of the peripheral and deep tumor margins developed in the...
