A case of adenocarcinoma with clear cell carcinoma of the bladder.

A case of adenocarcinoma with clear cell carcinoma of the bladder in a 65-year-old male is reported. Our patient had a walnut-sized nodular tumor located on the anterior wall of the bladder. The patient underwent radical cystoprostatectomy with urethral hemi-Koch pouch. Histopathological examination revealed a lesion composed of poorly-differentiated adenocarcinoma and clear cell carcinoma with diffuse sheet patterns of cells with abundant, clear cytoplasm. The patient died of general metastasis 18 months after operation. To our knowledge this is the first case of adenocarcinoma with clear cell carcinoma arising from the anterior wall of the bladder in a male.
