Paratubal cancer found at the time of laparoscopic surgery for adnexal torsion: a case report and literature review.

INTRODUCTION

Paratubal cysts are common incidental finding, but malignant paratubal cancers have rare occurrence and have not been sufficiently described and discussed in previous studies.

CASE REPORT: This report describes a case of a 70-year-old female who underwent emergent laparoscopy for adnexal torsion. A serous cystadenocarcinoma arising in a paratubal cyst and accompanied by tubal torsion was revealed by frozen section and successfully treated with laparoscopic cytoreductive surgery and adjuvant chemotherapy.

CONCLUSION

This report is the first case of paratubal cancer with bilateral tubal torsion which was diagnosed and treated with laparoscopic surgery, and the third report describing serous cystadenocarcinoma arising in a paratubal cyst. In the laparoscopic surgery for the paratubal cyst clinically presumed as accompanied with tubal torsion, surgeons should not ignore the possibility of malignancy in spite of the rare incidence of paratubal cancers and the preconception that adnexal malignancies are seldom accompanied by tubal torsion.
