GENERAL HISTOLOGY

Detailed explanation-1: -An ectopic pregnancy occurs when a fertilized egg implants and grows outside the main cavity of the uterus. An ectopic pregnancy most often occurs in a fallopian tube, which carries eggs from the ovaries to the uterus. This type of ectopic pregnancy is called a tubal pregnancy.

Detailed explanation-2: -In an ectopic pregnancy, the egg implants somewhere other than the uterus-often, in the fallopian tubes. This is why ectopic pregnancies are commonly called “tubal pregnancies.” The egg also can implant in the ovary, abdomen, or the cervix.

Detailed explanation-3: -An ectopic pregnancy occurs when a fertilized egg implants and grows in a location that cannot support the pregnancy. Almost all ectopic pregnancies-more than 90%-occur outside of the uterine cavity in a fallopian tube, but they can also implant in the abdomen, cervix, ovary, and cesarean scar.

Detailed explanation-4: -Usually, an ectopic pregnancy is implanted in one of the fallopian tubes. As it grows, if it is not diagnosed in time, it can cause the tube to tear or burst. This is called a ruptured ectopic pregnancy and results in dangerous internal bleeding. An ectopic pregnancy occurs in roughly one in 100 pregnancies.

Detailed explanation-5: -Differential Diagnosis Important differential diagnoses to consider with ectopic pregnancies are ovarian torsion, tuba-ovarian abscess, appendicitis, hemorrhagic corpus luteum, ovarian cyst rupture, threatened miscarriage, incomplete miscarriage, pelvic inflammatory disease, and ureteral calculi.
