Molecular genetic analysis of nongestational choriocarcinoma in a postmenopausal woman:  a case report and literature review.
Choriocarcinoma is a highly malignant tumor of trophoblastic origin. Most cases occur in association with preceding gestational events. However, on very rare occasions, nongestational choriocarcinoma arises from germ cell or trophoblastic differentiation in different types of carcinoma. This article reports the case of a 58-year-old woman with primary nongestational choriocarcinoma of the uterus that developed 19 years after her final pregnancy and 4 years after menopause. A total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed. Histopathological examination showed choriocarcinoma of the uterus without components of other germ cell tumors. Karyotype analysis of the tumor cells demonstrated XX. We confirmed its nongestational origin by DNA polymorphism analysis at 15 short tandem repeat loci. After surgery, the patient was given four courses of combination chemotherapy. She is still alive and there has been no evidence of recurrence 3 years after surgery.
