The patient was a 73-year-old man who visited our hospital with asymptomatic gross hematuria. Cystoscopy revealed a bladder tumor in two places. Serum prostatic specific antigen was normal (2.535 ng/ml). Transurethral resection of bladder tumors was performed. In order to complete resection of bladder tumor, transurethral resection of right lobe of the prostate whitch had protruded into the bladder, was needed. Histology of the prostatic tissue revealed squamous cell carcinoma with no grandular and acinar structures. Serum SCC-antigen level was evaluated (6.2 ng/ml) after establishment of the diagnosis. Thoraco-abdominal computed tomography and 18-fluorodeoxyglucose positron emission tomography/ computed tomography (18F-FDG PET/CT) showed prostate cancer and multiple metastases in the lymph nodes, such as right external iliac, right common iliac, para-aortic and left supraclavicular region. The patient received external radiation therapy to the prostate and underwent systemic chemotherapy using docetaxel. After 2 courses of docetaxel therapy, multiple lymph nodes metastases were reduced and serum SCC-antigen level was normalized. Docetaxel therapy could not be continued because of a side effect of interstitial pneumonia.
