PY - 2022 T2 - Williams Obstetrics, 26e AB - Gestational trophoblastic disease (GTD) is the term used to encompass a group of tumors typified by abnormal trophoblast proliferation. Trophoblast produces human chorionic gonadotropin (hCG). Thus, the measurement of this peptide hormone in serum is essential for GTD diagnosis, management, and surveillance. GTD histologically is divided into hydatidiform moles, which are characterized by the presence of villi, and nonmolar trophoblastic malignant neoplasms, which lack villi.
