Dermatology is the branch of medicine that is concerned with the diagnosis and treatment of diseases of the skin, hair, nails and adjacent mucous membranes. A dermatologist is the doctor who has been trained to identify and treat these conditions. Generally, when we think of dermatologists, the first things we think about are the acne skin problems many young people suffer from. While dermatologists work with many teens to resolve this problem, they perform many other kinds of diagnoses and treatments, as well.Dermatologists first go to medical school and then to a residency program for their specialized training. Depending on the doctor's specialty and interest, the dermatologist may train to treat both children and adults.Dermatologists receive very specialized training in the following areas: Diagnosis and treatment of skin cancers, melanomas, moles, and other tumors of the skin. Management of contact dermatitis and other inflammatory skin disorders, such as rashes. Diagnosis and treatment of skin manifestations of systemic and infectious diseases. Surgical techniques used in dermatology. Dermatologists also treat cosmetic disorders of the skin, including hair loss, scars, and the skin changes associated with the aging process. Some dermatologists perform cosmetic work such as botox and collagen injections and perform eyelid surgery and liposuction.There are sub-specialties within the medical field of dermatology. A dermatopathologist uses the microscope to diagnose skin diseases that are infectious, degenerative or related to the immune system. In order to do these examinations, the doctor uses specially prepeared tissue sections, cell scrapings and smears of skin lesions using a variety of micropscope techniques, including light microscopy, electron microscopy and fluorescence microscopy. Another sub-specialty, pediatric dermatology, focuses on skin diseases that are more common in children, including birthmarks and neonatal dermatology. These physicians often work with a medical teams treating children with multiple complex medical conditions.Once thought to be a lightweight specialty, dermatology is really a very critical specialty dedicated to the body's major organ — the skin.
