[PRIMARY SQUAMOUS CELL CARCINOMA OF THE PROSTATE: A CASE REPORT].

SQUAMOUS CELL CARCINOMA, prostate carcinoma, The patient was a 67-year-old man who visited our hospital with urge incontinence. His serum prostatic specific antigen level was normal (1.191 ng/mL). Digital rectal examination and magnetic resonance imaging suggested common prostatic carcinoma. A transperineal needle biopsy was performed, and the histological diagnosis was squamous cell carcinoma (SCC). The serum SCC-antigen level was normal, and the patient underwent a radical prostatectomy. Computed tomography 15 months later revealed multiple metastases in the lymph nodes. The patient underwent systemic chemotherapy using fluorouracil (5-FU) and cisplatin (CDDP). After 3 courses of chemotherapy, the multiple lymph node metastases could not be detected.
