| Indomethacin embryofetopathy refers to the manifestations that may be observed in a fetus or newborn when the mother has taken indomethacin, a potent prostaglandin inhibitor and tocolytic agent that can cross placenta, during pregnancy. Reported adverse fetal/neonatal effects include decreased renal function resulting in oligohydramnios, closure of the ductus arteriosus, and delayed cardiovascular adaptation at birth. These effects are usually transient and reversible. Indomethacin may also be a risk factor for cerebral injury (periventricular leukomalacia) and necrotizing enterocolitis in preterm infants. |

| A rare, inherited, epidermolysis bullosa simplex characterized by generalized severe blistering with widespread congenital absence of skin and pyloric atresia that is usually fatal in infancy. Antenatally, pyloric atresia can manifest with polyhydramnios. If patients survive, they experience life-long skin fragility and nail dystrophy. Additional extracutaneous findings include failure to thrive, anemia, sepsis, intraoral blistering, enamel hypoplasia, urethral stenosis and urologic complications. |

| Epignathus is a very rare and life threatening intraoral teratoma, usually arising from the maxilla, mandible, palate or base of skull and invading the cranium, nasopharynx or oral cavity. Epignathus is more commonly seen in females, and presents with various manifestations (depending on the tumour size) including obstructive polyhydramnios in the prenatal period and dyspnoea, cyanosis, cough, difficulty in sucking and swallowing, and rarely vomiting (due to swallowing difficulties) postnatally. When large, they can lead to airway obstruction, asphyxia and death in the neonatal period. |
