FIGURE 1

Figure 1: Microscopic examination of the nephrectomy specimen revealed an epitheloid tumor with large polygonal cells with eosinophilic cytoplasm and atypical nuclei with prominent nucleoli (HE). The tumor cells showed a positive reaction in the immunohistochemica stainings for HMB45 and MART1 (from left to right), but were negative for AE1/3 as well as PAX8 and SOX10 (not shown). Original magnification 100x, the length of the scale bar is 100痠

Figure 2: Microscopic examination of the metastasis specimen. The tumor cells showed a positive reaction in the immunohistochemical stainings for HMB45 and MART1 (from left to right), but were negative for AE1/3 as well as PAX8 and SOX10 (not shown). Original magnification 100x
