[Only metastasis to uterine corpus from superficial bladder cancer that of no original recurrence].

We report a rare case of uterine corpus metastasis from superficial bladder cancer. A 78-year-old female presented with abnormal vaginal bleeding. She received transurethral resection of bladder tumor (TUR-Bt) two years previously, and the pathological findings were transitional cell carcinoma (TCC) grade 3 pT1. Eight courses of BCG instillation were performed postoperatively. There was no recurrence of bladder cancer when vaginal bleeding occurred. Cytology of vaginal discharge was class V, and transitional cell carcinoma suspected. Pathological finding of transvaginal uterine corpus biopsy was TCC. We diagnosed metastases to uterine corpus from bladder cancer.
