Adenosquamous carcinoma (ASC) and sarcomatoid carcinoma (SC) of the prostate are rare, but highly aggressive tumors. The occurrence of mixed carcinomas in the prostate is even more rarely reported. The present study reports the case of a 62-year-old male who was diagnosed with prostatic adenocarcinoma accompanied by multiple bone metastases, as shown by a needle biopsy and skeletal computed tomography scan. The patient was treated with hormonal therapy, but thereafter, specimens from a transurethral resection of the prostate (TURF) were found to be composed of three histologically distinct elements: ASC, SC and adenocarcinoma. The level of p53 was evaluated by immunohistochemistry in detail, and it was found that this was significantly increased in the TURF samples compared with the needle biopsy samples. The abnormal level of p53 was likely associated with the prognosis of the patient; the patient succumbed to prostate carcinoma two months after the confirmation of the diagnosis.
