Dermatology is a branch of medicine dealing with the skin and its diseases. A doctor who specialises in this is called a Dermatologist. Dermatology involves but is not limited to study, research, and diagnosis of normal and disordered skin diseases, cancers, cosmetic and ageing conditions of the skin, fat, hair, nails and oral and genital membranes, and the management of these by different investigations and therapies. These may include but are not limited to dermatohistopathology, topical and systemic medications, dermatologic surgery and dermatologic cosmetic surgery, immunotherapy, phototherapy, radiotherapy and photodynamic therapy.

Referral Expectations
A dermatologist and a GP can, in some cases, diagnose skin conditions just by looking at them. The shape, size, colour and location are all assessed, as well as any other symptoms. At times a biopsy has to be taken so that a diagnosis can be made. A biopsy is the removal of a small piece of the skin/lesion for examination under a microscope. Minor surgery may be needed to perform this biopsy. In some cases the whole lesion will be removed and examined.
Another way a dermatologist can examine a skin disorder is by scraping some of the top layer of skin from the lesion/affected area. This is called a skin scraping. This scraping is also sent to the laboratory for examination.
Self reference is allowed.
