Low malignant potential serous tumors are the most common subtypes of non-benign serous tumors in the young, usually confined to one or both ovaries. To preserve ovarian function and fertility conservative management can be performed. Although recurrence is higher than that after a completion surgery, the rate of recurrences continues to be debated. Most recurrent diseases are of the same histopathology as the initial tumor and adequate excision of the recurrent tumor can be done.

A 31-year old, primigravid underwent bilateral oophorocystectomy for serous borderline ovarian tumor stage IB. After 3 years she had tumor recurrence and another fertility-sparing surgery consisting of left salpingooophorectomy and contralateral cystectomy was done. Histopathology was a recurrent borderline ovarian tumor. Two years later, she had a spontaneous pregnancy and delivered to a live term baby. This is a reported case of a successful pregnancy after two fertility-sparing surgeries for borderline ovarian tumor.
