title: Ovarian pregnancy presenting as ovarian tumour: report of 2 cases.
abstract: We present 2 cases of ovarian masses diagnosed as tumours but turned out to be pregnancy. Ovarian pregnancy, a form of ectopic gestation has a distinct pathology though it can be a source of diagnostic difficulty clinically and intraoperatively. A total of 71 ectopic pregnancies were seen in the department from January 2001 to December 2005, of these only two were ovarian ectopics. Both patients were nulliparous and presented with lower abdominal pains, abdominal masses and menstrual irregularity. They both had laparotomy and total right salpingo-oophorectomy. Grossly, the ovaries were enlarged, grey tan and globular. Focal ruptures in the wall of the ovaries showed protruding fetal parts. Microscopy showed chorionic villi within and in continuity with ovarian stroma and corpus luteum. They were both diagnosed ovarian ectopics. A good knowledge and understanding of the gross pathology, combination of imaging studies and high index of suspicion should help in making an intra-operative diagnosis.
