A Case of Partial Hydatidiform Mole with Coexisting Twin Pregnancy Following In Vitro Fertilization and Embryo Transfer / 대한산부인과학회잡지

Hydatidiform mole, characterized by abnormal fetoplacental development and placental villous trophoblast hyperplasia, results from genetically abnormal conception. Twin pregnancy consisting of hydatidiform mole (H-mole) and a coexisting fetus occurs with an estimated incidence of 1 per 10,000-100,000 pregnancies. There are several data which H-mole and a coexisting fetus can carry out viable fetus recently. However this unusual pregnancy has the risks of malignant change and severe medical complications, so it is a dilemma to decide continuation or termination of pregnancy. We present a twin pregnancy with partial H-mole and a coexisting fetus that occurred following IVF-ET, which was terminated at 16 weeks of gestation.

Recurred Giant Sacral Schwannoma: Report of a Case and Review of the Literature / 대한산부인과학회잡지

Retroperitoneal Schwannomas are mostly benign encapsulated neoplasms originating from the Schwann cells of the retroperitoneal peripheral nervous systems. They are rare, but when the tumors occur, they can be large and difficult to diagnose because of a wide variety of nonspecific symptoms and findings on radiologic studies. The treatment of choice is a simple enucleation but sometimes conservative approach is inevitable. There are some discrepancies of the prognosis of conservative approach. A 54-year-old woman presented with a 4 month history of voiding difficulty and abdominal palpable mass. She had a history of partial resection of mass which was diagnosed as a retropretoneal schwannoma nine years ago. Computerized tomography revealed bilateral hydronephrosis and a increased presacral mass that destructed sacrum. Left percutaneous nephrostomy was performed preoperatively. We performed a conservative core resection and ultrasonic aspiration of the mass because of its dense adherence to major nerves and iliac vessels. After operation, percutaneous nephrostomy were removed. Voiding difficulty and left hydronephrosis were disappeared but right hydronephrosis was remained with improvement. Double J catheter was inserted to right ureter. Five months after surgery, the size of remained mass is reduced and bilateral hydronephrosis were disappeared.
