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 (TURP) 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 TURP 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.
Bizarre leiomyomas of the scrotum are rare benign tumors that are often misdiagnosed. In this study, we present a case of bizarre leiomyoma of the scrotum in a 53-year-old male. The patient presented with a painless scrotal mass that was insidious in the right side of the scrotum with no sudden increase in size. Definitive preoperative diagnosis could not be established; however, following surgical resection of the tumor, a diagnosis of bizarre leiomyoma of the scrotum was determined by pathological examination. The patient was followed up six months following resection and no problems were reported. This is the first reported case of bizarre leiomyoma of the scrotum in China. A supplementary review of previously published cases and literature is also presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
