Vaginal and uterine anomalies in the paediatric and adolescent patient.

A number of case reports and surgical procedures have also been described, although they have contributed only minimally to our existing understanding. Data on prevalence has always been difficult in congenital abnormalities, and some data are also now emerging to support the figures quoted in the literature.
