A Case of Recurrent Endometriosis with Rectal Invasion

Rectal invasion of endometriosis is unusal condition, since it represents an invasion of previously normal bowel by hormone-dependent nonmalignant cell from uterus of the same patient. It is estimated that the incidence of endometriosis is about 8-15% of reproductive women, of whom 3-34% show intestinal invasion of rectosigmoid colon, appendix, ileum, and cecum in order of decreasing frequency. We experienced a case of recurrent endometriosis with rectal invasion in 34-year-old female who had previously endometriosis. She had rectal bleeding with severe anemia and abdominal pain with palpable mass in cul-de-sac. We present the case with a brief review of literature.
