        References

      Vulval lesions are not well described in the early medical literature, but first appear in the writings of Severinus Pineus in the sixteenth century and van den Spieghel in the seventeenth century. The terms used to describe the anatomical structures are often related to their function. The word vulva is derived from the Latin word for ‘wrapping’. The vagina (sheath) and mons veneris (hill of Venus) are obvious descriptions. The clitoris is usually thought to come from the Greek kleitoris, meaning ‘key’ or ‘gatekeeper’. Hymen is derived from the Greek hymen, meaning membrane. The labia are probably so called because they surround the vaginal opening like lips (Latin labium – lip).

      There is a very wide variation in the appearance of the normal vulva, and this chapter looks at the normal anatomy, anatomical variants, and normal histological features at different sites. It is vital to understand the normal before the abnormal is diagnosed, thereby avoiding unnecessary treatment and worry for the patient.
