title: AFP-producing urothelial carcinoma of the bladder: a case report.
abstract: We report a case of urothelial carcinoma of the urinary bladder with concurrent alpha-fetoprotein (AFP) elevation. A 60-year-old male was admitted for gross hematuria. Subsequent analyses revealed elevated serum AFP levels (970.20 ng/ml). He had no history of hepatitis, and hepatobiliary disease was not detected on computed tomography or ultrasound. Carcino-embryonic antigen was normal. The patient underwent radical cystectomy and was found to have a high-grade urothelial carcinoma of bladder on pathology. In addition, immunohistochemical staining of the tumor cells showed strong AFP positivity. Postoperatively, serum AFP levels decreased gradually to normal. In summary, urothelial carcinoma of the urinary bladder with AFP elevation is rare, and the mechanism and prognosis require further exploration.
