Keizo Dohi (土肥 慶蔵 Dohi Keizō, July 20, 1866 – November 6, 1931) (his pseudonym was Gakken) was a Japanese dermatologist and urologist. He was a professor of Dermatology and Urology at Tokyo University, he substantially introduced Western dermatology to Japan. Because he learned not only dermatology but also urology in Europe, Japanese universities created a Department of Dermato-urology, the separation of these two specialities took many years.
