33-year follow-up after simple excision of a giant renal oncocytoma with calcifications: case report and review of the literature.
Renal oncocytoma can present with calcification seen on the plain roentgenogram. From a review of the literature (both before and after 1976, when the concept of oncocytoma was popularized in the English literature), 10 cases of calcification in association with renal oncocytoma were found. In three of these 10 cases, the calcifications could be grossly demonstrated on the plain roentgenogram; in the other seven cases, the calcifications were microscopic in nature. The presence of calcification in a renal tumor does not rule out the diagnosis of oncocytoma. Grossly, a renal oncocytoma has a brownish mahogany color. A case is presented in which simple excision of an oncocytoma resulted in a 33-year survival. In the future, excision instead of nephrectomy could become the standard treatment for these tumors.
