[Adenocarcinoma of the bladder producing carcinoembryonic antigen and carbohydrate antigen 19-9: report of a case].
We report a case of primary adenocarcinoma of the bladder producing carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9). An 85-year old woman presented with gross hematuria. Computerized tomography and ultrasonography demonstrated a mass on the urinary bladder. After clinical examination, she was diagnosed with locally invasive bladder cancer. Serum CEA and CA19-9 levels were increased to 8.9 ng/ml (normal < 2.5) and 870 U/ml (normal < 37), respectively. Simple cystectomy and bilateral cutaneous ureterostomy were performed. The histopathological diagnosis was well-differentiated adenocarcinoma of the bladder with invasion through the entire muscle layer. Postoperatively, the serum CEA and CA19-9 levels decreased to 5.4 ng/ml and 53 U/ml, respectively, and both CEA and CA19-9 were detected by immunohistochemical examination of the tumor.
