Focal calcifications are frequently seen in renal masses and may be present in renal cell carcinomas. Metaplastic bone formation, on the other hand, is a rare event. We report a unique case of a large calcified renal cell carcinoma with massive osseous metaplasia and bone marrow elements. The clinical and pathologic differential diagnosis for this tumor is discussed along with a review of the literature on this unusual phenomenon.
局灶性钙化在肾肿块中很常见，也可能存在于肾细胞癌中。另一方面，化生骨形成是一种罕见的情况。我们报告了一例独特的病例，为一个伴有大量骨化生和骨髓成分的巨大钙化肾细胞癌。本文讨论了该肿瘤的临床和病理鉴别诊断，并对有关这一不寻常现象的文献进行了综述。
