Vulvar intra-epithelial neoplasia associated with other genital tract neoplasia. Four case reports and discussion.

It is recognised that a significant number of patients who develop vulvar intra-epithelial neoplasia (VIN), will have had previous genital tract neoplasia. This has resulted in speculation that there may be a common aetiology and, in particular, on the possibility of an infective element. Four such cases from the Vulva Clinic at the Western Infirmary, Glasgow are presented for discussion.
