Abstract

Five cases of ovarian serous borderline tumor associated with multiple peritoneal implants were analysed. The age of 5 patients ranged from 34 to 45(mean: 39) years at the time of diagnosis. Two patients presented with secondary infertility underwent hyperstimulation of the ovary under the in vitro fertilization program. One patient was presented with abdominal pain and the remaining two with lower abdominal mass accompanied by abdominal pain. Serous surface papilloma of borderline malignancy, involving one or both ovaries, was present in all 5 cases and papillary serous cystic tumor of borderline malignancy was associated simultaneously in one or both ovaries in all cases. Marked adhesions between the pelvic organs, and multiple granularities and nodularities of the omentum and peritoneum were noted. Microscopically, the peritoneal lesions were composed of noninvasive implants of tumor cells and pasmmoma bodies on the surface of entire pelvic and abdominal organs. Flow cytometric analysis of nuclear DNA content from paraffin-embedded tissue fo primary ovarian tumor classified as aneuploidy in 3 cases and as diploidy in 2 cases. The DNA index of the aneuploid tumors ranged from 1.21 to 1.37. Four patients underwent hysterectomy, bilateral salpingo-oophorectomy and partial omentectomy in which two were followed by chemotherapy and one case underwent bilateral salpingo-oophorectomy.
