Figure 2: (a) Tumor showing clear cells in the tubular pattern (asterisk) separated by smooth muscle fibers and blood vessels (hollow arrows), (b) clear cells showing low-grade nuclei and smooth muscle fibers (hollow arrows). Immunohistochemistry staining: (c) positivity for smooth muscle actin in stroma (solid arrows), (d) diffuse positivity for pan cytokeratin (cytokeratin 7) in tumor cells (hollow arrows), (e) negative for CD 10 in tubular cells (asterisk), (f) negative for myogenin (asterisk)
