Different histological subtypes of parotid gland tumors: CT findings and diagnostic strategy

Figure 4 Histopathological features of pleomorphic adenoma, basal cell adenoma, Kimura’s disease and Warthin’s tumor (HE staining, x 400). A: Pleomorphic adenoma are a large amount of myxoid matrix (arrow), rare epithelial components, and low micro vessel count; B, D: Basal cell adenoma and Warthin’s tumor (War-T) respectively, small capillaries and venules are prominent (black arrow). War-T consists of abundant lymphoid interstitial tissue and gland tube sample structures; C: Kimura’s disease demonstrates a lot of eosinophil invasion.
