[Rhabdoid tumor of the kidney arising in a newborn infant: description of a case with ultrastructural observations].
BACKGROUND
Rhabdoid tumour of the kidney is a new independent entity. Before it was considered a variant of Wilms tumor of the kidney. Now we have enough parametres to define the rhabdoid tumor: immunohistochemistry positive by the vimentin, special histological features and behaviour.


METHODS
We report a very aggressive case of rhabdoid tumor found in a two week old infant.


RESULTS
We studied aspects of histology and histochemistry. We found a positivity for vimentin and many cells in apoptosis.


CONCLUSIONS
The mild positivity for vimentin and the high number of cells in apoptosis suggest a relationship between apoptosis and behaviour.
