title: Paratubal serous borderline tumor.
abstract: Although paratubal cysts are well-characterized incidental findings, paratubal serous borderline tumors are very rare, with only one case report in the literature. We describe here a 27-year-old, nulliparous, married woman with a paratubal serous borderline tumor. The patient presented with a huge pelvic mass accompanied by flank pain and underwent paratubal cystectomy and fertility-sparing surgical staging procedures. Thirteen months after surgery, she delivered a healthy baby at term. She is well, without evidence of disease, 20 months after surgery. Because paratubal serous borderline tumors are very rare, their optimal management must be extrapolated from their ovarian counterparts.
