I would like to dedicate this edition to two true experts in vulval disease whom I have been privileged to work with and who continue to teach me

Sallie Neill, my mentor in this subject and good friend, for continuous support and encouragement in clinical scenarios, teaching and publication.

Micheline Moyal‐Barracco, my friend, teaching colleague, and collaborator, who always challenges me to think, learn, and develop new concepts.

It is now over 10 years since the 3rd edition of Ridley’s The Vulva was published. Since that time, my co‐editor for that book, Dr Sallie Neill, has retired but has trusted me to continue with this new edition. It aims to provide a comprehensive update but also to include more topics now encompassed by the field of vulval disease.

Significant changes have been made to this 4th edition, with a more contemporary feel and a format that is easier to navigate. The number of chapters has therefore been increased to include new and emerging subjects. There are several new authors, all experts in their fields, who help to discuss old subjects in new ways. With the addition of an online edition, it is possible to provide additional references, clinical and histological images, and other resources.

Despite all these changes, the aim of the book has not changed from Marjorie Ridley’s original vision, and it will keep her name to acknowledge her pioneering work in this field. I hope it will therefore be a useful resource for all those involved in the management of patients with vulval disease and hence ultimately improve care for this patient group.

Fiona M. Lewis

I would like to thank all the contributors for their hard work in revising the old and writing the new chapters. I am especially grateful to my dermatopathology colleague, Dr Eduardo Calonje, not only for providing histology slides but also for his superb dedication to clinicopathological correlation and for teaching me so much in our weekly meetings to review vulval pathology. Dr Ágnes Pekár‐Lukacs has scanned most of the new histology slides to provide excellent‐quality images, and her contribution to this book has been enormous.
