Dermatology
Dermatology
Dermatology is a branch of medicine dealing with the skin and its appendages (hair, nails, sweat glands etc). A medical doctor who specializes in dermatology is a dermatologist. A dermatologist is trained to diagnose and treat pediatric and adult patients with benign and malignant disorders of the skin (including skin cancers, melanomas and moles), mouth, external genitalia, hair and nails, as well as a number of sexually transmitted diseases.
Cosmetic dermatology
Cosmetic dermatology has long been an important part of the field, and dermatologists have been the primary innovators in this area. In the 1900's dermatologists employed dermabrasion to improve acne scarring and fat microtransfer was used to fill in cutaneous defects. More recently, dermatologists have been the driving force behind the development and safe and effective employment of lasers, new dermal filling agents (collagen and hyaluronic acid), botulinum toxin ("Botox"), nonabrative laser rejuvenation procedures, intense pulsed light systems, photodynamic therapy, and chemical peeling.
Dermatologists are specializing in the diagnosis and treatment of diseases and tumors of the skin and its appendages. There are medical and surgical sides to the specialty. Dermatologic surgeons practice skin cancer surgery (including Moh’s micrographic surgery), Laser surgery, photdynamic therapy (PDT) and cosmetic procedures using botulinum toxin ('Botox'), soft tissue fillers, sclerotherapy and liposuction. Dermatopathologists ermatopathologists interpret tissue under the microscope (histopathology). Pediatric dermatologists specialize in the diagnoses and treatment of skin disease in children. Immunodermatologists specialize in the diagnosis and management of skin diseases driven by an altered immune system including blistering (bullous) diseases like pemphigus. In addition, there is a wide range of congenital syndromes managed by dermatologists.
The residency training for dermatologists is three to four years. The three year program must be preceded by a year of broad-based clinical training (PGY-1). Practice in a dermatology subspecialty requires one additional year of training.
