Two cases of multilocular cystic renal cell carcinomas in a 48-year-old man and in a 41-year-old woman are reported. Radical nephrectomy was performed in both cases. Both histologic diagnoses were multilocular cystic renal cell carcinoma, clear cell subtype, grade 1. We had some difficulty in diagnosing the latter case with multilocular cystic mass which had smooth, glistening lining and contained clear-yellow fluid. Microscopical examination of the permanent sections revealed that the cysts were lined by a cuboidal or flattened epithelium, but no tumor cells. However, laminar growth of renal cell carcinoma of the clear cell type was present in several areas in the septa, and a few residual tumor cells were found in the hyalinized septa. When renal cell carcinoma is present in only a part of the multilocular cystic renal mass, it should be diagnosed as multilocular cystic renal cell carcinoma. The literature was surveyed.
报告了1例48岁男性和1例41岁女性的多房囊性肾细胞癌病例。两例均行根治性肾切除术。组织学诊断均为多房囊性肾细胞癌，透明细胞亚型，1级。我们在诊断后一例有多房囊性肿块的病例时遇到了一些困难，该肿块内衬光滑、有光泽，内含清亮黄色液体。永久切片的显微镜检查显示，囊肿内衬立方形或扁平上皮，但无肿瘤细胞。然而，在间隔的几个区域存在透明细胞型肾细胞癌的层状生长，并且在玻璃样变的间隔中发现了一些残留的肿瘤细胞。当肾细胞癌仅存在于多房囊性肾肿块的一部分时，应诊断为多房囊性肾细胞癌。并对相关文献进行了综述。
