Introduction: Primary squamous cell carcinoma of the prostate is an extremely rare tumor with poor prognosis. Squamous cell carcinoma of the prostate is estimated to comprise less than 1% of all prostate carcinomas. We report herein a case with clinical response to docetaxel, cisplatin, and 5-fluorouracil chemotherapy with radiotherapy, in a patient with metastatic squamous cell carcinoma of the prostate. Case presentation: A 74-year-old man consulted with frequent urination. The prostate-specific antigen level was 1.62 ng/mL. Multiparametric magnetic resonance imaging showed prostate imaging and reporting and data system category 5 for the whole prostate and biopsy was performed. The pathological diagnosis was pure squamous cell carcinoma of the prostate. fluorodeoxyglucose positron emission tomography showed fluorodeoxyglucose accumulation in the whole prostate and multiple pelvic lymph nodes. Four cycles of docetaxel, cisplatin, and 5-fluorouracil regimen were administrated along with radiotherapy. The patient showed a marked response with no major adverse events.
Conclusion:The present case suggests the potential of docetaxel, cisplatin, and 5fluorouracil chemotherapy with radiotherapy for squamous cell carcinoma of the prostate.
