摘要 目的探讨前列腺特异性间质肉瘤(prostatic special-ized stromal sarcoma,PSS)的临床病理学特点、免疫学表型、诊断和鉴别诊断要点。方法通过常规HE染色及免疫组织化学标记,对2例PSS进行显微镜下组织学形态观察,并进行文献复习。结果 PSS细胞呈梭形及短梭形,呈束状、编织状、车辐状或弥漫性浸润生长,瘤细胞胞质丰富、嗜酸,细胞核主要呈卵圆形、短梭形,核仁不明显,可见较多增生且扩张的厚壁血管。免疫组化染色显示肿瘤细胞vimentin、CD34呈阳性表达,大部分病例PR阳性表达。结论 PSS是来源于前列腺激素依赖性特异性间质细胞的一种少见肉瘤。病理诊断主要依靠病理形态学和免疫组织化学标记,CD34和PR阳性是诊断该肿瘤的重要参考依据之一,鉴别诊断主要包括孤立性纤维性肿瘤/血管外皮细胞瘤、平滑肌肉瘤、横纹肌肉瘤、恶性外周神经鞘瘤等。
