The patient was a 77-year-old man who visited our clinic with a chief complaint of dysuria. Digital rectal examination suggested prostatic carcinoma, but prostatic tumor marker levels were within normal limits. Transrectal needle biopsy was performed and histology was squamous cell carcinoma. Radical prostatectomy and pelvic lymph node dissection were performed with the diagnosis of T3N0M0 primary squamous cell carcinoma of the prostate. The 127 gm. tumor was moderately differentiated pT3N2M0 squamous cell carcinoma. Metastasis to the bilateral internal iliac arterial lymph nodes was confirmed histologically. Therefore, four courses of chemotherapy were performed using methotrexate, cisplatin, and pepleomycin. However, local recurrence was observed 11 months postoperatively and multiple pulmonary metastasis was developed at 13 months. The patient died of the disease 14 months after the operation. In Japan, seven cases of primary squamous cell carcinoma of the prostate have been reported, but none of these patients were treated by radical prostatectomy when the diagnosis was established by preoperative biopsy. In this case, changes in the squamous cell carcinoma antigen level in the blood corresponded to the effect of postoperat...Continue Reading
