Sarcomas and related proliferative lesions of the specialized stroma of the prostate are very rare and have been classified into prostate stromal sarcoma (PSS) and prostatic stromal tumor of uncertain malignant potential based on histology. We herein describe a case of PSS. A 40-year-old male presented at a hospital with urinary distention. Magnetic resonance imaging revealed a large prostate mass, and the diagnosis was prostate sarcoma of uncertain differentiation by ultrasound-guided needle biopsy. Total pelvic exenteration was performed and a pathological diagnosis of PSS was ultimately reached. Ten months later, there have been no signs of metastasis or recurrence.
前列腺特殊间质的肉瘤及相关增殖性病变非常罕见，根据组织学已被分为前列腺间质肉瘤（PSS）和恶性潜能不确定的前列腺间质肿瘤。我们在此描述一例PSS病例。一名40岁男性因尿潴留就诊于一家医院。磁共振成像显示前列腺有一个大肿块，经超声引导下针吸活检诊断为分化不确定的前列腺肉瘤。进行了全盆腔脏器切除术，最终病理诊断为PSS。十个月后，没有转移或复发的迹象。
