We report a case of choriocarcinoma of the fallopian tube which is exceedingly rare.<BR>A 49-year-old woman with her last pregnancy at age 31 years and menopause at age 47 years was referred to our hospital because of lower abdominal pain. A right adnexal tumor was suspected by findings from CT and echography. Endometrial aspiration cytology revealed Arias-Stella reaction, which indicated some trophoblastic disease. So we performed a total abdominal hysterectomy with bilateral salpingo-oophorectomy. The tumor measuring 7×4×4cm in the right fallopian tube was a necrotic and hemorrhagic mass. Histopathologic examination showed atypical trophoblastic cells with pleomorphic, hyperchromatic and multiple nuclei. Tumor cells were noted between the myosalpingeal fibers. Tumor emboli were observed within blood vessels in the tubal wall. No villi were present. The endometrium showed a characteristic Arias-Stella reaction, but no villi. These results lead us to conclude that this is a primary choriocarcinoma of the fallopian tube. Accordingly, it is suggested that aspiration cytology is useful tool to diagnose tubal trophoblastic disease.
