We encountered a case of Stage Ic ovarian serous borderline malignancy in t
he first trimester of pregnancy. At laparotomy, spontaneous rupture of the
capsule and a small amount of serous ascites was observed. Because of the l
aparotomy during pregnancy, correct staging of the tumor might not be perfo
rmed. This case presented a major problem in deciding the treatment strateg
y. which are reported here together with some discussion of the literature
on the preservation of fertility in borderline ovarian malignancy. (C) 2001
