The examination begins recording the patient’s medical history. The dermatologist will interview the patient in detail about their symptoms, previous illnesses, and previous disease that occurred in the family. The dermatologist will then examine the altered skin surface. If necessary, they take a closer look at the epidermis and the dermis with a magnifying glass or a special device with internal lighting and magnifying glass, called a dermatoscope.
If necessary, the dermatologist may order a blood test or refer you to another specialty, such as internal medicine, to rule out involvement of other organs, or to surgery to remove any skin lesions.
