Dr. Lawrence Jaeger of New York is an expert in the diagnosis and treatment of skin conditions and is board certified in dermatology and dermatologic surgery

A dermatologist is a physician who is trained to evaluate and treat children and adults with benign and malignant disorders of the skin, hair, nails and adjacent mucous membranes. A dermatologist has had additional training and experience in the following:

The diagnosis and treatment of skin cancers, melanomas, moles, and other tumors of the skin.
The management of contact dermatitis and other inflammatory skin disorders.
The recognition of the skin manifestations of systemic and infectious diseases.
Interpretation of skin biopsies.
Surgical techniques used in dermatology.
Dermatologists also manage cosmetic disorders of the skin, including hair loss, scars, and the skin changes associated with aging.
Trained dermatologists may combine several activities – seeing patients in public hospital clinics and/or in private practices, acting as consultants to other specialists, teaching, and participating in clinical research.

Dermatologists must have a working knowledge in basic sciences including microbiology, pathology, biochemistry, physics, physiology, and endocrinology. They must be familiar with all the other medical specialties because of their consultant work and because many skin diseases are associated with internal conditions.

Dermatologists perform skin surgery in many situations:
To prevent or provide early control of disease, e.g. remove skin cancer.
To improve the skin’s appearance by removing growths, discolourations, or damage caused by ageing, sunlight or disease.
To establish a definite diagnosis (biopsy).
Dermatologists perform many specialized diagnostic procedures including:
microscopic examination of skin biopsy specimens
cytological smears
patch tests
photo tests
potassium hydroxide (KOH) preparations
fungus cultures
and other microbiologic examination of skin scrapings and secretions.
Treatment methods used by dermatologists include:
externally applied, injected, and internal medications
selected x-ray and ultraviolet light therapy
a range of dermatologic surgical procedures.
laser and light therapies
