title: Paratubal borderline serous tumors.
abstract: BACKGROUND
  While ovarian borderline tumors are common, their fallopian tube counterparts are extremely rare. We describe the first case of a serous borderline paratubal tumor with a review of the literature on paratubal and tubal low malignant potential tumors.
  
  
  METHODS
  A 26 year-old woman presented with acute onset of sharp right lower quadrant pain and nausea. Abdominal and pelvic CT revealed 12.5 cm cystic ovarian mass and she was admitted for pain control. On hospital day two, her pain escalated and torsion was suspected; thus, she underwent a diagnostic laparoscopy with right fallopian tube cystectomy and partial salpingectomy. Inspection of the cyst wall demonstrated multiple papillary excrescences and frozen section returned at least borderline fallopian tube neoplasm. After a fertility-sparing comprehensive surgical staging procedure was performed, she was diagnosed with stage IC fallopian tube serous borderline tumor and underwent no further therapy. Currently, she is without evidence of disease recurrence.
  
  
  CONCLUSIONS
  Borderline fallopian tube or paratubal tumors are usually early stage at diagnosis and commonly present in the third decade with pain or are discovered on routine examination. Continued reporting of these tumors is essential to understanding the prognosis and treatment of this rare tumor.
