Fig. 5From: Clinicopathological and molecular study of 10 salivary gland clear cell carcinomas, with emphasis on rare cases with high grade transformation and occurring in uncommon sitesIHC for the CCC. The tumor cells were positive for (a) p63 (Case 1, IHC × 200) and (b) CK5/6 (Case 1, IHC × 200), and negative for (c) SMA (Case 2, IHC × 200), (d) calponin (Case 3, IHC × 100), (e) S-100 protein (Case 2, IHC × 200), and (f) SOX10 (Case 2, IHC × 200). (g) p16 expression was negative (Case 3, IHC × 200). (h) Different Ki-67 immunoreactivity was noted between the conventional region in the lower left corner (median, 1.9%) and the HGT region in the upper right corner (median, 42.5%) (Case 1, IHC × 100)Back to article page
