Summary

Genital chronic graft-versus-host disease (GVHD) in women posthaematopoietic cell transplantation may cause vaginal mucosal sclerosis. Human papillomavirus (HPV) reactivation, also common post-transplantation, limits local immunosuppressive, but not oestrogen treatment. A 36-year-old nulliparous woman developed coincidental genital chronic GVHD and HPV 22 months after transplant for aplastic anaemia. Topical immunosuppression for GVHD led to an eruption of warts successfully treated with laser surgery and cone biopsy. She maintained normal ovarian function and used extended cycle combined hormonal contraception. A vaginal oestrogen ring used continuously limited most scarring for 8 years. Progressive apical vaginal scarring obstructed menstrual flow leading to haematocolpos and haematometra. Normal anatomy was restored with a cruciate incision in the cervicovaginal scar performed during menses. When HPV disease limits use of topical immunosuppression in women with vaginal GVHD, the local scar-reducing effect of a vaginal oestrogen ring is limited, and surgery may be needed and can be successful in treating haematocolpos.This study was registered in ClinicalTrials.gov with trial registration number of NCT00003838.
