Fig. 3From: Clinicopathological and molecular study of 10 salivary gland clear cell carcinomas, with emphasis on rare cases with high grade transformation and occurring in uncommon sitesUncommon histological morphology in CCC. (a) The morphological contrast between the conventional low-grade region on the left and the HGT region on the right and the middle (Case 1, HE× 50). (b) The HGT area showing nuclear pleomorphisms, high nuclear-to-cytoplasmic ratios, high mitotic activity, and necrosis (Case 1, HE× 200). (c) Cystic changes were observed within the tumor nest, forming pseudopapillae (Case 1, HE× 100). (d) Gland-like spaces were focally identified (Case 5, HE× 200). (e) Entrapped non-neoplastic ducts (arrow) (Case 6, HE× 200). (f) Tumor cells were connected to the surface overlying epithelium (Case 7, HE× 100)Back to article page
