Increases of uterine cervical adenocarcinoma incidence have been observed in recent years. In this report, we present a rare case of cervical adenocarcinoma, which mimics vesicovaginal fistula. A 40-years-old multigravida patient presented with involuntary leakage of urine that began 6 months ago following dilatation and curettage for her pregnancy with missed abortion.During pelvic examination, exfoliation and wetness inperineum was observed but the 'cough stress test' was negative. Nulliparous healthy cervix with clear watery discharge was also observed. Laparotomy with total abdominal hysterectomy and abdominal washing were done. Histological examination revealed diagnosis of cervix adenocarcinoma without lymphovascular and perinueronal invasion and also endometrial adenocarcinoma located on two different focuses without myometrial invasion. An effusive watery vaginal discharge that evaluated mistakenly as urine may be produced by the malignant gynecological adenocarcinoma.
