Figure 3: Microphotographs of the renal tumor showing. (a) Tubular and solid nests of clear tumor cells with focal psammomatous calcification (arrow) and surrounding dense chronic inflammation and dilated blood vessels (H and E, ×100). (b) Papillary arrangement of tumor cells with clear and granular cytoplasm containing slender fibrovascular septae with lymphocytic infiltrate (H and E, ×200). (c) Magnified view showing enlarged nuclei of higher grade with nuclear prominent nucleoli (H and E, ×400). (d) Nuclear positivity of TFE3 in clear cells (Diaminobenzidine, ×400)
