[Patho-anatomical characteristics of renal cell cancer].
A total of 61 observations on nephrocellular cancer were carried out. It was established that the tumour was not uniform by its histological structure neither in the primary node nor in metastases. Four variants of a histological structure of the cancer were identified: clear-cell, granular, sarcoma-like, and grandular. The one-type histological structure (one variant) in the primary node and in the most common metastases was identified nearly with the same frequency--in 60-66% of the cases. In the rest of the cases the tumour was of a mixed structure; more often there were observed combinations of 2 variants and more seldom--of 3 or 4 combinations. As a rule, metastases histologically corresponded to the primary node, but had peculiar features of their own depending on their localization. Divercity of morphological structures of tumours should be born in mind in making the histological diagnosis of nephrocellular cancer, partitularly if the volume of tissues obtained is small.
