INTRODUCTION
Clear cell adenocarcinoma of the prostatic urethra in men is an extremely rare disease, with only eight case reports published.
CASE PRESENTATION
A 56-year-old man visited our hospital for gross hematuria. Urinary cytology detected class V, cystoscopy showed no abnormal findings, and contrast-enhanced computed tomography also showed no abnormal findings in his upper urinary tract except for a low-enhancement lesion on his left prostate lobe. Magnetic resonance imaging revealed a cystic lesion surrounding the prostate that was suspected of being urethral or prostate cancer, so transurethral resection was performed. A papillary tumor was detected at the prostatic urethra, and after resecting this tumor, a cavity showing multiple tumors was observed. The final pathological diagnosis was clear cell adenocarcinoma. Laparoscopic radical cystectomy and urethrectomy were thus performed. The pathological diagnosis was the same as at the primary tumor site.
CONCLUSION
We herein report a case of clear cell adenocarcinoma of the prostatic urethra.
引言
男性前列腺尿道透明细胞腺癌是一种极为罕见的疾病，仅有八例病例报告发表。
病例介绍
一名56岁男性因肉眼血尿前来我院就诊。尿液细胞学检查发现为V级，膀胱镜检查未发现异常，增强计算机断层扫描显示其泌尿系统除左前列腺叶有一个低增强病变外也未发现异常。磁共振成像显示前列腺周围有一个囊性病变，怀疑是尿道或前列腺癌，因此进行了经尿道切除术。在前列腺尿道发现一个乳头状肿瘤，切除该肿瘤后，观察到一个有多个肿瘤的腔隙。最终病理诊断为透明细胞腺癌。因此进行了腹腔镜根治性膀胱切除术和尿道切除术。病理诊断与原发肿瘤部位相同。
结论
我们在此报告一例前列腺尿道透明细胞腺癌病例。
