Diagnostic work-up for rectovaginal endometriosis. (a) Colposcopic appearance of the posterior fornix with reddish vegetations and a bluish nodule (arrow). C = cervix. (b) Histologic preparation of vaginal endometriosis. A cyst lined by endometrial-type mucosa and containing menstrual debris is evident under the stratified squamous epithelium. (hematoxylin and eosin, magnification: ×10) (c) A transrectal median sagittal ultrasound scan with 6.5-MHz probe shows a 25-mm retrocervical endometriotic nodule distorting the anterior rectal wall. (d) Schematic representation of Figure 1c. C = cervix; E = endometriotic nodule; R = rectum; V = vagina.
