The patient is a 25-year-old woman, gravida 0, who was referred to the gynecology oncology division at Chonnam National University Hospital with lower abdominal pain and abdominal mass. Her gynecologic history was unremarkable. Physical examination was notable for abdominal mass that was near at xiphoid process. Pelvic ultrasound revealed about more than 20 cm cystic mass. Magnetic resonance imaging of the pelvis revealed about 23×21×9 cm sized serous borderline cystic tumor in the right ovary and 2.2 cm corpus luteum of the left ovary. There was no remarkable findings in the uterus and no abnormal pelvic lymphadenopathy. The tumor marker profile was as follows: CA-125 38.2 U/mL (0-35). Another tumor markers and the result of hematological analyses were within their normal ranges.\nExploration of the abdominopelvic cavity revealed about 23 cm sized brownish fluid contained cyst located within the right fallopian tube. Its surface was clear and on cut section, it had multiple papillary growing in inner surface (). The left ovary had about 1 cm sized whitish nodule. A right salpingectomy, left ovary wedge biopsy, appendectomy and cytology were performed. A frozen section of the right fallopian tube revealed a serous borderline tumor. And a frozen section of the left ovary revealed a fibroma. Exploration of the right ovary and left tube was unremarkable, and, in view of patient's age and desire for future fertility, no further surgical procedure was undertaken. Histologically, right tubal mass was serous borderline tumor and appendix uninvolved by tumor cells and cytology of peritoneal washing fluid was negative for malignant cells. Tumor had cystic change and papillary nodules. On microscopic examination the papillae were covered by serous type of epithelium (), displaying stratification and budding with focal nuclear atypia (). There was no invasion of the supportive stroma of the papillae or into the fallopian tube wall. Micropapillary pattern of the tumor was absent and there was no papillary tubal hyperplasia in the fallopian tube. In general, the histology of the tumor was similar to that of an ovarian borderline serous tumor. Pathologic diagnosis was serous borderline tumor of the right fallopian tube. Close follow-up was recommended and currently, the patient's postoperative recovery was uneventful.
A 34-year old multigravida was found to have right adnexal mass on her routine gynecologic examination. Her previous medical history was uneventfull and Pap smear was normal. Transvaginal ultrasonography identified a cystic mass adjacent to the right ovary. Serum CA 125 was 5.1 U/ml (reference range: < 35 U/ml). At laparoscopy a dilated fallopian tube with bluish discoloration was found. The contralateral fallopian tube, ovaries and uterus were unremarkable. Exploration of the abdomino-pelvic cavity revealed smooth and shiny peritoneal surphace. Obtained peritoneal and pelvic washing were negative. Fine needle aspiration of dilated part of the fallopian tube revealed a 4 ml of bloody content. Cytological findings were consistent with hematosalpinx. Right salpingectomy was performed without using endoscopic bag. The patient was followed up by means of ultrasonography and serum CA 125 for 4.6 years. During this period she had no evidence of the disease.\nGrossly, a 7.0 cm long fallopian tube was irregularly dilated up to 4.4 cm in diameter at the ampulary region. The fimbriae were intact. The serosal surphace was smooth. Sections of the dilated part of the fallopian tube revealed a cystic tumor with focally yellow to tan, soft papillary excrescences protruding into the lumen (Fig. ) and foci of intracystic hemorrhage. On microscopic examination the papillae were covered by serous type of epithelium, displaying stratification and budding with focal nuclear atypia (Fig. ). Three types of cells were recognised; ciliated cells, hob-nail cells and mesothelium-like cells. Small foci of tumor tissue necroses and hemorrhage were noted. There was no invasion of the supportive stroma of the papillae or into the fallopian tube wall. Focus of endosalpingiosis within the adjacent mesosalpinx was found. DNA analysis determined by flow cytometry paraffin technique revealed DNA diploid tumor with low S-phase fraction of 6.5 %.
