[Sarcoidosis and clear cell carcinoma of the kidney: the sixth case?].

The Authors report a very rare case of clear cell renal cancer associated with sarcoidosis, incidentally discovered in a 39 year-old man, admitted for a not correlated pathology (multiple left rib fractures due to automobile crash). Problems related to a proper assessment of sarcoidosis are discussed as well as potential arising of a neoplasm during the entire follow-up period: for that, it must always be complete and accurate.
