Prostate stromal sarcoma is quite rare, comprising only 0.1-0.2% of all prostate cancers. Here, we report one case of prostate stromal sarcoma in a 38-year-old man. Initially, the patient suffered from lower urinary tract symptoms, and intravenous pyelography showed a larger filling defect in the bladder. Transrectal ultrasound showed a huge heterogenous mass between the bladder and rectum. Abdominal computed tomography revealed prostate tumor with local invasion. Radical cystoprostatectomy with ileal conduit was performed; pathology revealed high-grade prostate stromal sarcoma with invasion to the right seminal vesicle and urethra. This article describes the pathology and immunohistrochemical features of this case and briefly reviews the literature.
前列腺间质肉瘤非常罕见，仅占所有前列腺癌的0.1 - 0.2%。在此，我们报告一例38岁男性的前列腺间质肉瘤病例。最初，该患者出现下尿路症状，静脉肾盂造影显示膀胱内有较大的充盈缺损。经直肠超声显示膀胱和直肠之间有一个巨大的异质性肿块。腹部计算机断层扫描显示前列腺肿瘤伴局部侵犯。行根治性膀胱前列腺切除术并留置回肠导管；病理显示为高级别前列腺间质肉瘤，侵犯右侧精囊和尿道。本文描述了该病例的病理和免疫组织化学特征，并简要回顾了相关文献。
