A 31-year-old G1 P0 patient with a history of infertility presented with li
ght spotting and cramping at the end of her first trimester, An ultrasonogr
am at 19 weeks gestation revealed an intrauterine gestation of 21 weeks, a
large leiomyoma, and a 8.9 x 6.8 cm complex left ovarian mass. At 35 weeks
gestation she had an emergency cesarean section and left salpingo-oophorect
omy due to a presumed ruptured ovarian mass. The ovarian mass was diagnosed
as a serous cystadenocarcinoma. An exploratory laparotomy with a total abd
ominal hysterectomy, a right salpingo-oophorectomy, omental biopsy, and per
iaortic node sampling at 9 weeks postpartum revealed a diagnosis of stage I
C ovarian serous cystadenocarcinoma and a stage IA secretory endometrial ad
enocarcinoma. Adjunctive P-32 therapy was successfully administered and at
this time the patient has had no recurrence. (C) 1999 Academic Press.
