background and aim: horseshoe placenta is a variant of ring-shaped placenta. ring-shaped placenta is a rare anomaly seen in fewer than 1 in 6000 deliveries, which could be seen as horseshoe shape due to atrophy in a portion of the ring. this report refers to a possible relationship between the horseshoe shape placenta and preterm labor; although it has not been yet validated in the literature. ...

Placental mesenchymal dysplasia (PMD) is a rare benign placental abnormality. It is characterized by hydropic degeneration of stem villi, placentomegaly, and increased maternal serum alpha-fetoprotein(AFP). It can be associated with different congenital abnormalities, karyotype abnormalities, and feto-maternal morbidities. It is difficult to differentiate PMDfrom partial mole, complete mole wit...

Abnormality of the placental vasculature affects placental thickness. Abstract. 31 Background. Our empirical modeling suggests that deformation of placental vascular growth is 32

To determine whether placental abnormality (placental abruption or placental previa) during pregnancy predisposes an infant to a high risk of sudden infant death syndrome (SIDS), the authors conducted a population-based case-control study using 1989-1991 California linked birth and death certificate data. They identified 2,107 SIDS cases, 96% of whom were diagnosed through autopsy. Ten controls...

Introduction: Placental teratoma is an uncommon, non-trophoblastic benign tumor. Since the first description of this type tumor by Morvilli in 1925, only a few cases abnormality have been diagnosed and reported. Case presentation: We describe here 35-year-old pregnant woman admitted for elective cesarean section. The placenta membranes were delivered spontaneously. After delivering placenta, ma...

Examination of an infant born after prenatal diagnosis of mosaic partial trisomy 17q2 showed the unique phenotypic features of this chromosomal abnormality, that is, frontal bossing, large mouth, brachyrhizomelia, and hexadactyly. Amniocentesis was performed because of polyhydramnios and ultrasound diagnosis of fetal craniofacial dysmorphology and rhizomelic shortening of the limbs. Chromosomal...

ackground: Microscopic examination of placental tissue may provide a route to assessing risk and understanding underlying iology of autism. ethods: Occurrence of a distinctive microscopic placental morphological abnormality, the trophoblast inclusion, was assessed using rchived placental tissue. The rate of occurrence of trophoblast inclusion-positive slides observed for 13 individuals with aut...
