Abdominal pregnancy is one of the rare but extremely harzardous complications of childbearing. The diagnosis of the abdominal pregnancy is rarely made before surgery and the management of it also has many difficult problems. I experienced a case of abdominal pregnancy developed after the previous unilateral adnexectomy and it was a suspicious primary abdominal pregnancy as though did not fulfilled the Studdiford's the following criteria for primary abdominal pregnancy. 1) Normal tubes and ovaries with no evidence of recent or remote injury, 2) absence of any evidence of uteroplacental fistula, and 3) presence of a pregnancy related exclusively to the peritoneal surface and young enough to eliminate the possibility of secondary implantation following primary nidation in the tube. And now I present a case with brief review of literatures.
