| Résumé: | A 72-year-old woman with asymptomatic macrohematuria was referred to our hospital. Cystoscopy revealed a 7 cm sessile tumor on the left lateral wall of the bladder. Subsequently an intravenous pyelography revealed left hydronephrosis. We performed transurethral biopsy and resection of the bladder tumor under the diagnosis of ordinary malignant bladder tumor. Histopathologically, the lesion was shown to be an undiffentiated urothelial carcinoma, G3, > or = pT2, containing syncytiotrophoblastic giant cells. The level of serum human chorionic gonadotropin-beta (hCG-beta) level was slightly elevated (0.3 ng/ml; normal value: < 0.1). Because a further examination revealed an invasion into the surrounding fat tissue of the bladder and left ureter, a total cystohysterectomy with an ileal conduit were performed. The final histopathological classification was choriocarcinoma of the urinary bladder, pT3a, pN1, pMx. An adjuvant combination chemotherapy was carried out using methotrexate, vinblastine, adriamycin and cisplatin (MVAC). After two courses of chemotherapy, the serum hCG-beta levels returned to normal. Eleven months postoperatively, however, there was evidence of multiple lung metastases. The patient died 12 months after the surgery as a result of complications caused by widespread metastases |
