Metastases of Renal Cell Carcinoma to the Thyroid Gland with Synchronous Benign and Malignant Follicular Cell-Derived Neoplasms

Figure 2

Concurrent renal cell carcinoma and thyroid carcinoma. (a) Thyroidectomy specimen showed synchronous foci of metastatic clear cell renal cell carcinoma (top) and papillary thyroid carcinoma (bottom) (hematoxylin and eosin). The characteristic clear cell cytoplasm of the renal cell carcinoma (b) and the peculiar nuclear features of papillary thyroid carcinoma (c) are seen at a higher magnification (hematoxylin and eosin).
