Tumor cells were expressing S100 protein strongly and diffusely (Figure 1(e)) and CD68 in cytoplasmic inclusions surrounded by halos (Figure 1(f)) and were completely negative for p53 (Figure 1(g)), pancytokeratin (cytokeratin AE1/AE3), estrogen receptor, and progesterone receptor. This evidence concerns the gene TP53 and neoplasm.
