Ruptured extrauterine pregnancy: Human embryo from an extrauterine pregnancy (tubal pregnancy, or fallopian tube pregnancy, 6th week p.c., 8th week of pregnancy).

Crown-rump length is about 9-13mm.

When nidation of a fertilized ovum takes place outside of the uterine cavity, i.e. an ovum nests outside of the uterine cavity, this is called ectopic pregnancy.

99% of all ectopic pregnancies are located in one of the fallopian tubes (tubal pregnancy, or fallopian tube pregnancy). There are three possible sites:

  1. ampullary pregnancy:in the distal region of the fallopian tube
  2. isthmc pregnancy: a little further proximal, in the isthmic region
  3. interstial/intramural pregnancy: in the transition zone between fallopian tube and uterus

1% of ectopic pregnancies nest themselves in the ovar, the peritoneum, or the cervix uteri.
