The authors report 2 cases of ovarian pregnancy at Gynecological Obstetric Clinic of University Teaching Hospital in Dakar out of 210 ectopic pregnancy registered in a 28 month period (March 91 to June 93). These are the fourth and fifth cases operated on in Dakar (the 3 first cases are reported during the last 10 years). In light of the 2 cases using the data of the literature, the authors try to find out the particularities of the scarce affection which etiopathogeny is still unclear even if the symptomatology is often similar to a tubal pregnancy. The diagnosis is often evoked during laparatomies but its confirmation is based exclusively on the anatomopathological test. The frequent existence of intra ovarian hematoma and zones of necrosis make people practise annexectomy which should be avoid as much as possible.
