Bone metaplasia in a case of bilateral renal cell carcinoma.
We present a case of synchronous, bilateral renal cell carcinoma with osseous metaplasia. In renal cell carcinoma, bone can originate through two different processes: osseous differentiation or osseous metaplasia. The case we report here represents the second process. We discuss pathological differential diagnosis and prognosis of the infrequent tumor.
