子宮癌の再発が疑われた尿道淡明細胞腺癌の2例

Abstract

Herein, we report two cases of urethral clear cell carcinoma in two patients who had previously undergone radical hysterectomyfor utetine cancer. Case 1 presented with bloodyvaginal discharge and case 2 presented with acute urinaryretention. Magnetic resonance imaging revealed a periurethral tumor in both cases. Both cases were suspected to be recurrence at first. However, pathological findings of the transurethral resection-biopsyshowed clear cell adenocarcinoma in both cases. Subsequentlyradical cystourethrectomy and pelvic lymphadenectomy were performed in both cases. Surgical findings showed tumor invasion of the vaginal muscularis in case 1 and invasion of the anterior wall of the vagina and bladder neck in case 2. Although adjuvant postoperative therapywas not performed, there has been no evidence of recurrence to date.
