目的：探讨多囊性肾透明细胞癌的临床病理特点。方法：对1例多囊性肾透明细胞癌进行了免疫组化染色，并进行文献复习。结果：本例右肾肿物18年。大体见肿物由多发不等的囊腔组成。镜下囊内壁主要由单层立方或柱状上皮被覆，部分为rn多层并有乳头形成。瘤细胞胞质透亮，无明显异型性。癌细胞免疫表型cytokeratin、CEA和vimentin呈阳性表达。本例诊断为多囊性肾透明细胞癌。结论：多囊性肾透明细胞癌是一种罕见的肾癌病理类型。临床上主要采用根治切除术。本瘤的生物学行为属于低度恶性肿瘤。%To study the clinical and pathological features and biologic behavior of multilocular cystic renal clear cell carcinoma(MLCRCCC). Methods A case of MLCRCCC was stained with immunohistochemistry and the literature was reviewed. Results The tumor was found in right kidney eighteen years before diagnosis. The majority of carcinoma cells showed cytokeratin,CEA and vimentin positivities by immunohistochemical staining. Conclusion MLCRCCC is a rare histologic subtype of renal cell carcinoma and usually cured by radical surgery. It originates from tubular epithelial cells of the kidney and appears to be a low - graded malignant neoplasm.
