[Oncocytoma and calcification. A rare association].

The oncocytoma constitutes 3-6% of the kidney neoplasiae. The authors report one case of calcified kidney tumor, Its presentation as a calcified kidney mass is exceptional and is not present in the largest series of calcified kidney tumors. The calcification prognosis is much debated, even more in the case of oncocytoma due to the very limited series available. For calcified kidney tumor, the oncocytoma should be included as one of the differential diagnosis, even if it is not very frequent.
