Invasive hydatidiform mole is a type of neoplasia that grows into the muscular wall of the uterus. It is formed after conception (fertilization of an egg by a sperm). It may spread to other parts of the body, such as the vagina, vulva, and lung. See also

Ectopia cordis (Greek: "away / out of place" + Latin: "heart") or ectopic heart is a congenital malformation in which the heart is abnormally located either partially or totally outside of the thorax. The ectopic heart can be found along a spectrum of anatomical locations, including the neck, chest, or abdomen. In most cases, the heart protrudes outside the chest through a split sternum. Pathology
Ectopia cordis results from a failure of proper maturation of midline mesoderm and ventral body wall (chest) formation during embryonic development. The exact etiology remains unknown, but abnormalities in the lateral body wall folds are believed to be involved. Normally, the lateral body walls are responsible for fusion at the midline to form the ventral wall. Corruption of this process may underlie ectopia cordis.Defective ventral body wall formation yields a heart unprotected by the pericardium, sternum, or skin. Other organs may also have formed outside the skin, as well. Many cases of ectopia cordis have associated congenital heart defects, in which the heart has failed to properly form.Defects more commonly associated with ectopia cordis include:
Intracardiac defects
Atrial septal defect
Ventricular septal defect
Tetralogy of Fallot
Tricuspid atresia
Double outlet right ventricle
Non-cardiac malformations
Pentalogy of Cantrell
Omphalocele
Anterior diaphragmatic hernia
Cleft palate

Diagnosis
The Diagnosis of ectopia cordis is found with a routine ultrasound as early as the first trimester or the beginning of the second trimester. Treatment
Due to the rarity and rapid postpartum mortality of ectopia cordis, limited treatment options have been developed. Only some successful surgeries have been performed as of now, and the mortality rate remains high.
