OBJECTIVETo explore the pathologic features and prognosis of early and late onset severe preeclampsia.
METHODSAn observational study was conducted in 178 cases of severe preeclampsia collected during January 2010 to December 2014 from Haidian Maternal and Child Health Hospital.The cases were divided into two groups according to the onset of gestational age of the severe preeclampsia, with 54 cases of namely early onset (onset ≤ 34 weeks) and 124 cases of late onset (onset >34 weeks). Clinical characteristics of the patients, perinatal outcome and the pathologic characteristics of the placentas in each group were evaluated.
RESULTSDecidual vascular disease, placental infarction, abruptio placentae and placental villi dysplasia were seen in both groups. The incidence of placental villi dysplasia was the highest, followed by placental infarction. Incidence of severe decidual vascular disease of early and late onset severe decidual vascular disease were 16.7% (9/54) and 5.6% (7/124), respectively.Incidence of placental infarction of early and late onset severe preeclampsia were 48.1% (26/54) and 61.3% (76/124). Incidence of placental villi dysplasia of early and late onset severe preeclampsia were 79.6% (43/54) and 50.8% (63/124). Incidence of Severe decidual vascular disease, placental infarction and placental villi dysplasia were significantly different between early and late onset severe preeclampsia cases (P<0.05), while there was no difference in decidual vascular disease and placenta thrombi (P>0.05). Fetal survival rate of every group was 81.5% (44/54) and 93.5% (116/124). Incidence of fetal growth retardation was 55.6% (30/54) and 38.7% (48/124). The fetal survival rate and incidence of fetal growth retardation were different between two groups (P<0.05).
CONCLUSIONSThe incidence of decidual vascular disease and placental villi dysplasia in early onset severe preeclampsia is higher than those in late onset severe preeclampsia. Neonatal outcome and prognosis in early onset severe preeclampsia are worse than those in late onset severe preeclampsia.

OBJECTIVETo investigate the etiology, pathogenesis, clinicopathologic characteristics, clinical prognosis and treatment of Dandy-Walker syndrome.
METHODSNine cases of Dandy-Walker syndrome were included in the study. The autopsy findings and clinical history were evaluated along with review of the literature. The causes, pathogenetic mechanism, pathologic features and prognosis of Dandy-Walker syndrome were analyzed.
RESULTSAmong 9 Dandy-Walker syndrome cases, six patients presented with variants of Dandy-Walker complex and 3 cases had classic Dandy-Walker malformation. In addition, 4 patients presented with combined lateral ventricle expansion and multiple malformations were seen in 7 cases. Combined umbilical cord abnormality was noted in 4 patients with variant of Dandy-Walker complex and combined placental abnormality was seen in one classic Dandy-Walker syndrome.
CONCLUSIONSDandy-Walker syndrome is a rare disease. In addition to complex pathogenesis with possible genetic and environmental antigenic etiologies, placental and umbilical cord abnormality may be also related to its development.

OBJECTIVETo study the pathogenesis, pathologic features and prognosis of fetal nuchal cystic hygroma.
METHODSForty autopsied cases of fetal nuchal cystic hygroma were collected during January 2003 to December 2012. The clinical history, pathologic changes and immunohistochemical (EnVision method) findings were reviewed, and the pathogenesis and pathologic characteristics were analyzed.
RESULTSOf the 40 cases, 16 (40.0%) showed single malformation and 24 (60.0%) were associated with multiple malformations in other organs and/or systems.Nineteen cases were septated and 21 were not. The associated malformations occurred in the respiratory system, skeletal system and urinary system.In the cases of combined malformations of umbilical cord, 3 were single umbilical artery malformations and 1 was torsion and stricture of umbilical cord.Four cases had chromosomal analysis, and all were trisomy-21.
CONCLUSIONSFetal nuchal cystic hygroma is a rare disease. The etiology is unknown, but it is not neoplastic.Lymphangioma is divided into 3 types:capillary lymphangioma, cavernous lymphangioma and cystic hygroma according to their expansile growth pattern. The overall prognosis is determined by any co-existing chromosomal anomalies, associated malformations and the time of diagnosis of the cystic hygroma.

OBJECTIVETo study the etiology, pathogenesis, clinicopathologic characteristics, prognosis and treatment of congenital pulmonary airway malformation (CPAM).
METHODSEighteen cases of CPAM were enrolled into the study. The clinical history, autopsy findings and immunohistochemical results were evaluated, with review of literature. The pathogenetic mechanism, pathologic features and differential diagnosis of CPAM were studied.
RESULTSHistologic examination showed that 2 cases were classified as Stocker type I, 12 cases as type II, and 4 cases as type III. The lesion was unilateral and involved single lobe in 13 cases. The remaining 5 cases had bilateral diseases. Of the 18 cases studied, 12 cases showed single organ involvement and 6 cases had malformations affecting multiple organs. The associated malformations included cardiac anomalies (4 cases), polycystic kidney with gastrointestinal atresia (1 case) and nuchal cystic hygroma with hydrothorax (1 case).
CONCLUSIONSCPAM is a rare pulmonary disorder. The etiology of this non-neoplastic condition is unknown. Imaging analysis is a valuable tool to suggest CPAM, while definite diagnosis requires pathologic examination. The overall prognosis is determined by the presence of associated malformations, fetal hydrops and pulmonary hypoplasia.
