Vaginal adenosis is a benign abnormality in the vagina, commonly thought to be caused by intrauterine and neonatal exposure of diethylstilbestrol and other progestogens and nonsteroidal estrogens, however it has also been observed in otherwise healthy women and has been considered at times idiopathic or congenital.
[4] Risk is however still present in subsequent generations due to recent exposure.
[5] It is thought steroid hormones play a stimulatory growth in adenosis formation.
[7][8] Colposcopically, it presents itself similarly to columnar epithelium on the cervix, assisted with lugol's solution application for diagnosis.
[3][9] It can be discovered as nodules or cysts on the vaginal tube, with biopsy needed for further diagnosis.
