Overview

Causes

The causality of gestational trophoblastic neoplasia based on the subtypes is as follows:

Hydatidiform mole

  • Complete mole arises when an ovum without maternal chromosomes is fertilized by one sperm which duplicates its DNA, resulting in a 46XX androgenetic karyotype.[1][2]
  • Partial moles are almost always triploid, resulting from the fertilization of a healthy ovum by two sperms.[3][4][5]

Choriocarcinoma

  • Abnormal trophoblastic population undergoing hyperplasia and anaplasia can give rise to choriocarcinoma.[6]
  • Gestational type arises following a hydatidiform mole, normal pregnancy, or most commonly, abortion.[7]
  • Non-gestational type arises from pluripotent germ cells.[7]

Placental-site Trophoblastic Tumor (PSTT)

  • It arises from the placental implantation site when the trophoblastic cells infiltrate the myometrium.[8]

Epithelioid Trophoblastic Tumor (ETT)

  • It arises from the intermediate trophoblastic cells of chorion laeve.[9]
