Clinical presentation of incisional (cesarean section scar) endometriosis vary with the size of the lesion (Letters to the editor)

Endometriosis is described as a growth of ectopic endometrial tissue outside the uterine cavity which usually occurs in pelvic sites like ovaries, posterior cul-de-sac, ligaments of uterus, pelvic peritoneum and rectovaginal septum. It consists of 8 % 15 % of all menstruating women and responds to hormonal stimulation. Extrapelvic sites of endometriosis are less common, including nearly every organ, such as lung, appendix, nose, umblicus, peritoneum, even intestinal wall (1).
