What this specialty covers

A dermatologist is trained to diagnose and treat pediatric and adult patients with benign and malignant disorders of the skin, mouth, external genitalia, hair and nails, as well as a number of sexually transmitted diseases. The dermatologist has had additional training and experience in the diagnosis and treatment of skin cancers, melanomas, moles and other tumors of the skin, the management of contact dermatitis and other allergic and nonallergic skin disorders, and in the recognition of the skin manifestations of systemic (including internal malignancy) and infectious diseases. Dermatologists have special training in dermatopathology and in the surgical techniques used in dermatology. They also have expertise in the management of cosmetic disorders of the skin such as hair loss and scars and the skin changes associated with aging.

Reading the sole-proprietor share

For this specialty, 3,447 records, or 16.9%, carry the sole-proprietor flag in NPPES. This self-reported field is an imperfect proxy for private practice because it does not by itself show whether a dermatologist owns a practice, works independently, or operates outside an employed or group setting.
