Book excerpt: Correct diagnosis in dermatology depends largely on the identification and interpretation of clinical signs. The book is written by an international team of dermatologists, obstetricians and gynecologists and is the only comprehensive obstetric and gynecologic dermatology atlas covering evaluation, diagnosis and management. The obstetric content includes skin diseases and manifestations of systemic disease, which have an effect on the reproductive system, and the impact of pregnancy on the skin. Normal physiologic changes in the skin in pregnancy are also covered, along with the effects of vulvar viral disease and connective tissue disease on pregnancy. The second half of the book is devoted to discussing the many facets of vulvar dermatoses. The many updates and changes make the book accessible for the non-dermatologist reader.
