Placental site trophoblastic tumour is a rare gestational trophoblastic tumour (GTT) which develops from the placental implantation site and always occurs following pregnancy, voluntary termination of pregnancy (VTP) or miscarriage. Indicative signs are irregular metrorrhagia some time after spontaneous miscarriage or VTP, presence of metastasis or unexplained metrorrhagia in the weeks and months following normal childbirth or ectopic pregnancy. Chorionic gonadotropin (hCG) levels are usually low at about 10 to 100 IU/l (N < 2 to 5 IU/l).
