Borderline endometrioid tumor arising in a paratubal cyst: a case report.

Abstract

BACKGROUND:

Paratubal cysts, generally known as hydatid cysts of Morgagni, are small round cysts attached by a pedicle to the fimbriated end of the tube. The following represents the first reported case of an endometrioid tumor of low malignant potential arising in a paratubal cyst.

CASE REPORT:

A 45-year-old nulliparous female was referred with a complex right adnexal mass on pelvic sonogram. She underwent laparoscopic bilateral ovarian cystectomy and partial right salpingectomy (for a 3-cm torsed paratubal cyst). All frozen-section diagnoses were benign; however, final pathology revealed a borderline tumor of low malignant potential of endometrioid type in the right paratubal cyst. The patient underwent extensive counseling regarding management options and decided to have a laparoscopic right salpingo-oophorectomy. Final pathologic analysis revealed no evidence of persistent borderline tumor.

CONCLUSION:

Paratubal cysts are very difficult to diagnose with sonography; therefore, their management should be approached as any other adnexal mass. Laparoscopic surgery is an option in the management of adnexal masses; however, rupture or puncture of masses should be avoided when possible to prevent potential tumor dissemination in the event of a malignancy.
