A serous borderline tumor of the fallopian tube detected incidentally / 대한산부인과학회지

ABSTRACT

Serous borderline tumors (SBTs) of the fallopian tube are very rare and usually diagnosed incidentally. We present a case of SBTs of left fallopian tube incidentally diagnosed during laparoscopic hysterectomy because of increasing symptomatic myoma. Preoperative abdomino-pelvic CT revealed 6 cm sized myoma in uterus but no gross lesion on both adnexa. Preoperative serum CA 125 was 18.9 U/mL. At laparoscopy a 2.0 cm sized polypoid mass protruding from the ampulla portion of the left tube was found. The contralateral fallopian tube, ovaries and uterus were unremarkable except previous known uterine myoma. Exploration of the abdomino-pelvic cavity has shown no abnormal finding. Intraoperative frozen biopsy to tubal mass suggested borderline malignancy but did not completely rule out tubal carcinoma. So, standard laparotomy staging operative procedures such as hysterectomy, bilateral salpingooophorectomy, omentectomy, lymph node dissection, and appendectomy were performed. Serous borderline tumor limited tube was confirmed in permanent pathology. In English literature, only 7 cases have been reported. And the current case is the first report in Korean as far as we know. Treatment for SBTs of fallopian tube is complete excision like borderline ovarian tumor. Recurrence was not reported with up to 6 year follow up in 7 cases.
