Basal cell carcinoma of the prostate: a case report

A 69-year-old man presented with gross hematuria and irritative urinary symptoms. He underwent transurethral resection of his prostate. The prostate chips revealed 70% poorly differentiated carcinoma with neuroendocrine features, initially read as small cell carcinoma, later as basal cell carcinoma. PSA at this time was 0.3. He received 4 cycles of etoposide and cisplatin. After which, rebiopsy of the prostate showed tumor consistent with poorly differentiated basal cell carcinoma. Given progression on chemotherapy, decision was made to proceed with radical prostatectomy. Metastatic workup was negative. Gross extraprostatic invasion was noted but lymph nodes were free of metastatic disease.
