There are few areas in medicine where more interdisciplinary cooperation is required than in obstetric and gynecologic dermatology. This is reflected both in the mix of editors of this book (3 dermatologists and 2 gynecologists) and in the efforts of a gynecologist (D.R.D.) and dermatologist (W.B.) to review the text. We both feel that Martin Black, Marilynne McKay, and colleagues have produced an extremely valuable source of information for specialists in both fields as well as for the curious student or family physician.
