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 30-year-old woman visited the outpatient clinic seeking treatment for abdominal\ndistention present since the last 4 months. She had no history of surgery. Bowel and\nbladder functions were normal. Menstruation was regular and without any pain. The\npatient was nulliparous. Computed tomography (CT) scan with contrast showed a thin\nwalled unilocular cyst arising from the left adnexa with dimensions of\n22.3 cm × 18.4 cm × 6.8 cm; no papillary projections or nodules were observed (). The Ca 125 level\nwas 13.64 U/mL.\nBecause of the large size of the cyst and the patient’s preference, a laparotomy was\nperformed. We performed a midline incision above the umbilicus, trying to\nexteriorize the cyst without any rupture. Intraoperative exploration showed a large,\nthin-walled, unilocular cyst arising from the left para-tubal tissue without any\nadhesions; the left tube and left ovary were normal (). The para tubal cyst was dissected\nto separate it from the normal ovary and tube (). The para tubal cyst was removed\nand sent for histopathological examination (). The left tube and left ovary were\npreserved (). The\nuterus and right adnexa were normal. Frozen section examination confirmed by final\nhistopathological examination revealed a benign serous cyst of size\n22 cm × 17 cm × 6 cm.\nWritten, informed consent was obtained from the patient for the publication of this\nreport and its accompanying images ().
