We present an autopsy case of a two-day-old female infant with a very unusual combination of neuroblastoma in situ in both adrenals and microcephaly. This baby was born to a 28-year-old mother after 38 weeks of gestation, and died of respiratory difficulty 2 days later. At autopsy, the baby weighted 1,840gm, and the brain was extraordinarily small with a weight of 125gm. The gyral pattern was simplified and irregular. Microscopically massive migration defects, pachygyria, micropolygyria, leptomeningeal glioneuronal islands, small corticospinal tract and heterotopic Purkinje cells in the cerebellum were found. In addition, there were medullary nodules in both adrenals. They measured 0.7 x 0.4cm and 0.7 x 0.3cm, respectively. These nodules showed the typical histological features of undifferentiated neuroblastoma. The tumor nodules were confined to the medullary portion and did not extend to the cortex or contiguous structures meeting the criteria of neuroblastoma in situ. Based on these unusual and seemingly unrelated sets of findings, it is suggested that the histogenesis of neuroblastoma in situ could be a part of the generalized dysontogenic process.

Fetal cystic hygroma is a rare developmental congenital anomaly of the lymphatic system, characterized by the formation of a multilocular, variable sized cystic mass. Most of cystic hygromas are found in the neck and other rare locations include axilla, mediastinum, and limbs. There are many papers about cystic hygroma colli, but there are only a few papers about fetal axillary cystic hygroma and no domestic papers. We present a case of fetal axillary cystic hygroma diagnosed antenatally followed by full-term delivery in a 30-yr-old woman. Operation was performed on the 8th day after birth and the mass was excised and confirmed as cystic hygroma.

Nonimmune hydrops fetalis is becoming a predominant form of fetal hydrops due to the declining incidence of immune hydrops fetalis triggered by Rh isoimmunization. Infantile polycystic kidney appeared to be related to hydrops fetalis whether it is causal or merely coincidental and may represent another entry to differential diagnoses. Infantile polycystic kidney was diagnosed by an elevated maternal serum alpha-fetoprotein (AFP) value coupled with an ultrasonographic abnormality scanned as a multicystic mass with ascites in the fetal abdomen antenatally. This study presents a case of infantile polycystic kidney that resulted in a stillborn baby with hydrops fetalis and extensive placental calcification; it was the first case in Korea in which nonimmune hydrops fetalis was associated with infantile polycystic kidney in consecutive siblings by autosomal recessive inheritance in one family. In addition, this paper comprehensively reviews the incidence, etiology, prenatal diagnosis and proper management of nonimmune hydrops fetalis.

OBJECTIVETo summarize the clinicopathological features and prognosis of malignant ovarian neoplasms complicating pregnancy and explore the rational treatment.

METHODSThe clinical data of 38 patients with malignant ovarian neoplasms complicating pregnancy were retrospectively analyzed,and the intra-surgical pathological sections were reviewed. International Federation of Gynecology and Obstetrics (FIGO) staging system (1988) was applied.

RESULTSOf these 38 patients,the malignancies included epithelial ovarian cancer (n=9, 23.7%), epithelial borderline ovarian tumor (n=13, 34.2%),ovarian malignant germ cell tumors (n=11, 28.9%), sex cord stromal tumors (n=3, 7.9%), and metastatic tumor from gastrointestinal tracts (n=2, 5.3%). Twenty-seven patients (71.1%) were at stage I. The pregnancy outcomes included termination in the first trimester (n=8), full-term vaginal delivery (n=6), full-term Cesarean section (n=15), and therapeutical Cesarean section for premature birth (n=9). One newborn died,and the remaining 29 survived in a healthy status. All patients underwent surgical treatment,among whom two patients received surgeries during pregnancy. Patients were followed up for (40.5±38.5) months,during which one patient was lost to follow-up, 7 died, 1 survived with tumor, and 29 (76.3%) survived free of tumors.

CONCLUSIONSThe management of ovarian malignancies complicating pregnancy should be individualized. Both surgical treatment and chemotherapy are relatively safe in the second and third trimesters. Satisfactory prognosis can be expected after appropriate treatment.

OBJECTIVETo investigate the clinicopathological characteristics, diagnostic criteria and differential diagnosis of placental chorioangioma.

METHODSTwenty-five cases of placental chorioangioma were analyzed for their clinical data, histomorphology and immumohisto chemical staining. Relevant literature was reviewed.

RESULTSThe average age of the 25 patients was 29 years. Fourteen patients had full-term pregnancy, 10 had preterm labor, and 1 had intrauterine fetal death. Nineteen patients had pregnancy complications. The tumors presented as red or dusty pink nodules with clear borders. The tumor size ranged from 1 to 16 cm. Microscopically, the tumors possessed abundant capillaries or cavernous blood spaces lined by hyperplastic endothelial cells. These cells were positive for CD34 and Ki-67 index < 10%.

CONCLUSIONSPlacental chorioangioma is a rare benign tumor of the placenta, and is associated with various pregnancy complications. Misdiagnosis of cell-rich type tumor should be avoided.

Antepartum pituitary necrosis is a rare medical condition that has only been reported in pregnant women with type I diabetes attributable to diabetes-related vasculopathy and hypercoagulability. We present for the first time a case of antepartum pituitary necrosis occurring in an uncontrolled gestational diabetes mellitus (GDM) patient. The patient was a 32-yr-old woman at 33 weeks and 2 days of gestation. She suffered from severe headache, blurred vision, dizziness, and vomiting. Her baby was delivered by Cesarean section. The brain magnetic resonance images revealed pituitary necrosis. This suggests that pituitary gland necrosis may also complicate GDM pregnancy when glucose levels are uncontrolled.
