The skin is the largest organ, and as such can develop numerous different problems. These problems range all the way from rashes to skin cancers. In all, there are more than 3,000 different skin conditions. As dermatologists, we are asked daily to evaluate a substantial number of these, diagnose them, and treat them.
In many cases the diagnosis is based off what we can see visually with the spots in the skin, including their appearance and location. However, in a sizable portion of the cases, additional testing is often needed to better clarify the diagnosis – of all these tests, the skin biopsy procedure is most central.
