Because it is difficult histologically to differentiate between a renal cell carcinoma and a renal adenoma, their differentiation has been based on size. Lesions less than 3 cm. have been called adenomas and those greater than 3 cm. carcinomas. It is a widely accepted concept that adenomas evolve into adenocarcinomas, and it is true that lesions less than 3 cm. rarely metastasize. However, as demonstrated by this case and others, metastasis can occur, therefore, it is suggested that the term renal adenoma no longer be used.
由于在组织学上很难区分肾细胞癌和肾腺瘤，它们的区分一直基于大小。小于3厘米的病变被称为腺瘤，大于3厘米的则为癌。腺瘤会演变成腺癌，这是一个被广泛接受的概念，而且小于3厘米的病变很少发生转移，这也是事实。然而，正如本病例及其他病例所示，转移是可能发生的，因此，建议不再使用肾腺瘤这一术语。
