RESUMO
Uterine choriocarcinoma developing in patients beyond reproductive age is a rare occurrence. We report a case of choriocarcinoma of uterine corpus in a 54-yr-old woman after 7 yr of menopause and 25 yr after last child birth. She presented with pain in the abdomen, and on radiological investigation a left uterine adnexal mass of 3.4 x 2.8 cm size was detected. Her serum CA125 level was 40 mIU/mL (normal up to 35 mIU/mL). Hysterectomy revealed an intramural growth in left uterine cornu measuring 3.5 x 3.0 x 2.5 cm. Histological features of the tumor were consistent with choriocarcinoma, and immunohistochemistry detected strong reactivity for beta-hCG in the tumor cells. Serum beta-hCG level 4 wk after surgery was 1345 mIU/mL. The patient was put on combination chemotherapy (EMACO). She achieved serological remission but showed a rise in serum beta-hCG level 4 wk after completion of chemotherapy. We conclude that a high level of suspicion may help in preoperative diagnosis of uterine choriocarcinoma in the postmenopausal age group. However, the response to chemotherapy in these cases may not be as encouraging as in choriocarcinoma of reproductive age.
