摘　　要：目的:探讨肾乳头状腺瘤(RPA)合并多发性肾血管平滑肌脂肪瘤(RAML)的临床病理学特征、诊断及鉴别诊断要点。方法:应用光镜、免疫组织化学检测对1例RPA合并多发性RAML标本进行观察。结果:肾内肿瘤包括以梭形细胞为主的RAML与一境界清楚的RPA;免疫组化标记梭形肿瘤细胞阳性表达HMB45、S-100、CD34,而CK7、上皮膜抗原(EMA)、波形蛋白(vimentin,Vim)和结蛋白(desmin,Des)表达呈阴性。RPA细胞呈立方状或柱状,其细胞阳性表达CK7、CD10和EMA,而HMB45、S-100、Vim、结蛋白则呈阴性。结论:RPA合并多发性RAML极罕见,其组织起源目前仍有争议,其诊断及鉴别诊断主要依靠组织病理学、免疫组织化学检查。Objective To investigate the clinicopathologic features and differential diagnosis of papillary adenoma with angiomyolipoma in the kidney. Methods A papillary adenoma with angiomyolipoma in the kidney in a female case was investigated pathologically by light microscopy and immunohistochemical stains. Results The patient complained of pain in the right flank and hematuria. Histologically, the tumor exhibited features of typical angiomyolipoma and welldefined papillary adenoma. The spindle cells were positive of HMB45, S-100, CD34, and negative of CK7, EMA, vimentin and desmin determined by immunohistochemical staining. Papillary adenoma was positive of CK7, EMA, CD10, and negative of HMB45, S-100, vimentin and desmin. Conclusions The papillary adenoma with angiomyolipoma in the kidney is a rare renal neoplasm and its pathogenesis is controversial. The diagnosis and differential diagnosis mainly relies on histopathology and immunohistochemistry.
