Endometriosis is characterized by the presence of functional endometrial tissue outside uterine cavity. It was first described by Daniel Shroen, a German physician in 1690. This is a chronic condition affecting over 10% of reproductive age females but can affect all age women. The most common sites of endometriosis are ovaries, followed by other pelvic organs but sometimes can be found outside the pelvis.
Deeply infiltrating endometriosis is defined by the presence of endometrial implants penetrating under the peritoneal surface or under the wall of the pelvic organs to a depth of at least 5 mm. vaginal endometriosis can take the form of polypoid mass or as brownish cystic areas involving posterior vaginal fornix. It has been called as ‘‘adenomyotic nodule of rectovaginal septum. Vaginoscopy shows the presence of polypoid or cystic lesions, from 0,5 cm to more than 2, affecting the posterior vaginal fornix. Koninckx suggested that the ‘‘endometriotic’’ nodule is the consequence of deep infiltration by active disease
