[Primary squamous cell carcinoma of the prostate forming a rectourethral fistula: a case report]

Eleven cases of squamous cell carcinoma of the prostate have been previously reported in the Japanese medical literature. Patients with this type of carcinoma have dismal prognoses. Herein, we report a case in a 61-year-old man who was admitted to our hospital and whose chief complaints were dysuria and high fever. Pyuria, bacteriuria, and the results of a digital rectal examination suggested acute prostatitis. Despite the administration of antibiotics, the dysuria did not improve. A transrectal needle biopsy was performed, and histology of the tissue showed squamous cell carcinoma. After chemotherapy using methotrexate, pirarubicin, and cisplatin, total pelvic excentration was performed. At 12 months after the operation, the patient is alive with no evidence of the disease.
