Characteristics of clear cell renal cell carcinoma metastases to the thyroid gland: A systematic review

Figure 7 Illustrates immunohistochemical stains for thyroid transcription factor-1 and thyroglobulin in a case of clear cell renal cell carcinoma with thyroid metastases. A: Immunohistochemically stain showing positive thyroglobulin on right side coinciding with normal thyroid architecture and negative on the left; B: Immunohistochemically stain for thyroid transcription factor-1 which is positive on the right correlating with normal thyroid architecture and negative on the left where the metastatic renal cell carcinoma is present (Magnification x 100).
