Cystic masses are among the most common sonographically detectable abnormalities of the umbilical cord. Umbilical cord cysts have been described in association with fetal anomalies, with chromosomal or structural defects being found in over 20% of cases. We present a case of umbilical cord cyst associated with fetal death at 29 weeks of gestation with a brief review of literatures.

2.Primary borderline parovarian tumor in pregnancy.
Obstetrics & Gynecology Science 2015;58(6):533-536
There are few reports of pregnancy complicated by a primary borderline parovarian tumor. A 32-year-old pregnant woman was found to have an ovarian tumor. At 13 weeks of gestation, cystectomy was performed and a diagnosis of primary borderline parovarian tumor was made. At 38 weeks of gestation, she underwent cesarean section combined with a restaging operation. A normal infant was delivered and there were no signs of recurrence. Currently, the patient is being followed for 24 months after the initial treatment and all imaging data show no evidence of recurrence. This report includes a short review of the existing literature on this topic and documents this case in detail. This case demonstrates the appropriate procedure for evaluating and treating a primary borderline parovarian tumor during pregnancy.

Adrenocortical carcinoma (ACC) in pediatric and adolescent patients is rare, and it is associated with various clinical symptoms. We introduce the case of an 8-year-old boy with ACC who presented with peripheral precocious puberty at his first visit. He displayed penis enlargement with pubic hair and facial acne. His serum adrenal androgen levels were elevated, and abdominal computed tomography revealed a right suprarenal mass. After complete surgical resection, the histological diagnosis was ACC. Two months after surgical removal of the mass, he subsequently developed central precocious puberty. He was treated with a gonadotropin-releasing hormone agonist to delay further pubertal progression. In patients with functioning ACC and surgical removal, clinical follow-up and hormonal marker examination for the secondary effects of excessive hormone secretion may be a useful option at least every 2 or 3 months after surgery.

Obstetrics & Gynecology Science 2015;58(5):427-430
Congenital afibrinogenemia/hypofibrinogenemia is a rare inherited hematologic disorder in which a patient lacks or has insufficient level of fibrinogen, the blood coagulation factor I. The incidence of this uncommon disease is 1 to 2 per 1 million individuals. Hence, massive hemoperitoneum caused by ovulation in a woman with congenital afibrogenemia is also a very rare clinical condition. Massive hemoperitoneum usually presents as acute abdominal pain with potential findings of peritonitis including abdominal distention, hypotension and tachycardia with critical consequences. We performed emergent endoscopic surgery for hemoperitoneum caused by a ruptured corpus luteum cyst in a patient with congenital hypofibrinogenemia. To the best of our knowledge, this was the first case report of such treatment in Korea.

When retroperitoneal leiomyosarcoma develops in pelvic cavity, it often presents similar symptoms and radiological findings to adnexal tumor, therefore obscures diagnostic approaches until an exploratory laparotomy is performed. We report an unusual presentation of retroperitoneal leiomyosarcoma mimicking an adnexal tumor with extremely elevated serum CA-19-9. Though the most of the prominent mass was removed during surgery, there was massive bleeding due to tearing of internal iliac vein while dissecting the ureter close to vessels. This case focuses on the significance of considering retroperitoneal tumor even if the mass is located in ovarian fossa and has highly elevated serum level of CA-19-9. And in attempt of tumor removal, the excision needs to be clean-cut without damaging nerves or vessels around the mass and avoid causing any prospective complications.

Cavernous hemangiomas rarely involve the female genital tract. It is difficult to identify vascular malformations when these lesions are concealed in the vagina or deep vulva area. We present a rare case of vaginal cavernous hemangioma in a 30-year-old primiparous woman with an early severe postpartum hemorrhage (PPH) and delayed continuous bleeding from the episiotomy site. She was treated successfully with transarterial embolization of the left vaginal artery. To our knowledge, this is the first reported case of PPH caused by rupture of a vaginal hemangioma during vaginal delivery in English literature.

Posterior reversible encephalopathy syndrome (PRES) is a transient clinical neuroradiological disease entity characterized by clinical signs and symptoms including hypertension, generalized seizure, mental status change, headache, and vision change. It is most commonly reported in the literature in association with obstetrical patients suffering from preeclampsia and eclampsia. Two theories of vasospasm and vasogenic edema have been suggested to explain cerebral abnormalities associated with eclampsia. But, the pathophysiology of PRES remains unclear. Here we present one patient who suffered from eclampsia complicated by PRES and we could assume the pathophysiological mechanism in the development of PRES through this case.

Carboplatin, an advanced anticancer drug with excellent efficacy against ovarian cancer, was developed to alleviate the side effects that often occur with cisplatin and other platinum-based compounds. Our study reports the in vitro characteristics, viability, and activity of cells expressing the inducible nitric oxide synthase (iNOS) gene after carboplatin was conjugated with polysuccinimide (PSI) and administered in combination with other widely used anticancer drugs. PSI, which has promising properties as a drug delivery material, could provide a platform for prolonging carboplatin release, regulating its dosage, and improving its side effects. The iNOS gene has been shown to play an important role in both cancer cell survival and inhibition. Herein, we synthesized a PSI-carboplatin conjugate to create a modified anticancer agent and confirmed its successful conjugation. To ensure its solubility in water, we further modified the structure of the PSI-carboplatin conjugate with 2-aminoethanol groups. To validate its biological characteristics, the ovarian cancer cell line SKOV-3 and normal ovarian Chinese hamster ovary cells were treated with the PSI-carboplatin conjugate alone and in combination with paclitaxel and topotecan, both of which are used in conventional chemotherapy. Notably, PSI-carboplatin conjugation can be used to predict changes in the genes involved in cancer growth and inhibition. In conclusion, combination treatment with the newly synthesized polymer-carboplatin conjugate and paclitaxel displayed anticancer activity against ovarian cancer cells but was not toxic to normal ovarian cancer cells, resulting in the development of an effective candidate anticancer drug without severe side effects.

PURPOSE: Patients with serious burns are prone to chondritis due to lack of soft tissue in the auricle, which can cause severe defects in the auricular morphology. In addition, skin damage occurs frequently in the vicinity of post-burn wounds, presenting difficulties in reconstruction surgery. An auricular reconstruction has functional and cosmetic significance. The aim of this study is to develop appropriate reconstruction methods for auricular defects. METHODS: Thirty seven patients, who were treated for auricular defects from 2005 to 2009, were enrolled in this study. A local flap, multiple regional flaps and cartilage framework with or without a temporal fascial flap were applied in reconstruction surgery according to the location of the auricular defect. RESULTS: The age of the subjects ranged from 11 to 56. Some subjects had defects that cover more than half of the helical rim with most exhibiting post-burn scars in the vicinity, for whom a multiple regional flap was used. A single use of a tubed flap was sufficient for subjects with defects that covered less than half of the helical rim. A regional flap was also used for reconstruction in subjects with defects covering both the helical rim and antehelix. CONCLUSION: Achieving satisfactory results from the skin flaps and skin grafts for post-burn auricular defects in both functional and cosmetic aspects is a difficult task. Therefore, selecting an appropriate surgical method through proper diagnosis of the auricular defect and the state of the available skin in the vicinity is essential.

The incidence of pregnancy in a rudimentary uterine horn is very rare. We experienced a case of unruptured rudimentary uterine horn pregnancy in the first trimester. The patient was diagnosed by laparoscopy and removed by laparoscopic resection of the pregnant rudimentary uterine horn. We report our case with brief review of literatures.
