Hydatidiform mole in a 56-year-old woman.

We present a rare case of a hydatidiform mole that occurred in a 56-year old woman. The main symptom was prolonged vaginal bleeding, and the gynaecological examination revealed a markedly enlarged uterus. Sonography revealed a 9 x 15 cm large cystic tumour in the pelvis. At operation, a suspicion of trophoblastic disease was arosen. Serum human chorion gonadotropin was still markedly elevated on the fifth postoperative day. After removal of the uterus and adnexae the recovery and the 3-year follow-up have been uneventful.
