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.
