Rare primary abdominal ectopic pregnancy in the pouch of Douglas.

A 35-year-old Nepalese woman, referred by her general practitioner for per vaginal spotting and abdominal pain for the past 12 days with a background history of 5 weeks of amenorrhoea and a quantifiable beta-human chorionic gonadotrophin of 18 900 IU/L. Subsequent pelvic ultrasound revealed a cystic lesion with peripheral vascularity in the pouch of Douglas indicating possible ectopic pregnancy with no intrauterine gestational sac seen. Subsequent to that, she underwent a diagnostic laparoscopy that revealed 150 mL of blood in the pouch of Douglas with no other obvious evidence of tubal or ovarian ectopic pregnancy seen. There was, however, a resemblance of trophoblastic tissue noted on the wall of the pouch of Douglas that was further investigated to reveal a primary ectopic pregnancy of the pouch of Douglas with no trophoblastic infiltration.
