Dermatology is the study of all disorders related to the skin. Because venous diseases directly affect the skin, dermatologists need to have a basic understanding of phlebology. Historically, dermatologists have made brilliant contributions to the field of phlebology. Ambulatory phlebectomy was fathered by Robert Muller, a Swiss dermatologist. The cornerstone in the treatment of venous insufficiency, compression therapy and sclerotherapy were developed by Austrian and German dermatologists. Knowledge of wound healing and new ulcer dressings would not have been possible without key contributions made by dermatologists.
