Gestational trophoblastic disease (GTD)

Overview

Gestational trophoblastic disease (GTD) is a kind of tumor that is distinguished by aberrant trophoblastic growth. Human chorionic gonadotropin is produced by trophoblast cells (hCG). GTD is classified into two types: hydatidiform moles (which contain villi) and other trophoblastic neoplasms.

GTD that is non-molar or malignant is referred to as gestational trophoblastic neoplasia (GTN). Invasive moles, choriocarcinoma, placental site trophoblastic tumor, and epithelioid trophoblastic tumor are among them. These cancers can develop weeks or years after a pregnancy, although they are most frequent after a molar pregnancy.
