title: Paratubal borderline tumor diagnosed in the adolescent period: a case report and review of the literature.
abstract: BACKGROUND
  Borderline paratubal cysts are rare entities. These tumors are identified as epithelial proliferation without stromal invasion.
  
  
  METHODS
  A 19-year-old virgin patient was admitted to our clinic with abdominal pain and nausea. The sonographic evaluation showed a left adnexal mass 89 × 80 mm in diameter with solid tissue projections. Doppler examination revealed no significant blood supply. At surgery, a torsed left paratubal cyst 10 cm in diameter and normal bilateral ovaries were encountered. Cystectomy was performed and of frozen section revealed a borderline Fallopian tube neoplasm. Final pathology review was reported as a serous borderline paratubal tumor.
  
  
  CONCLUSIONS
  The evaluation of the structure of cyst by ultrasound and the performance of intraoperative frozen section analysis are two important issues to diagnose the nature of a cyst. Fertility-sparing surgery is the main point of management.
