The second edition of the textbook ‘Rare and Uncommon Gynaecological Cancers’ is a result of the COST Action GYNOCARE (CA18117), which was a 4-year project (2019–2023) funded by the European Cooperation in Science & Technology program (EU COST). GYNOCARE is the European network for Gynaecological Rare Cancer research: From Concept to Cure. The aim of this book is to review most of the relatively uncommon and rare gynaecological cancers and provide guidance on how best to manage these patients by multidisciplinary teams. The introductory chapters cover broad topics such as epidemiology, histopathology, molecular profiling, and imaging. Subsequently, there are specific sections for tumours of the ovary, of the uterus, and of the cervix, vagina, and vulva, followed by chapters on paediatric gynaecological tumours and fertility preservation, as well as trophoblastic tumours. This book is a handy reference for trainers and trainees.
