  		FIG 1. Power Doppler sonogram of a normal lymph node shows hilar vascularity.FIG 2. Power Doppler sonogram of a lymph node with Kimura disease shows hilar (arrow) and capsular (arrowheads) vascularity.FIG 3. Power Doppler sonogram of a lymph node with Kimura disease shows exaggerated hilar vascularity.FIG 4. Transverse gray scale sonogram shows an ill-defined, hypoechoic, heterogeneous nodule with cystic areas within (arrows) in the superficial lobe of the parotid gland (arrowheads).

  		FIG 5. Power Doppler sonogram of a lymph node with Kimura disease shows predominant hilar vascularity (arrowheads). Note the displacement of the hilar vessels by avascular cystic areas within the node (arrows).FIG 6. Power Doppler sonogram of an enlarged ear lobe shows hypoechoic internal echoes and multiple vessels scattered within.FIG 7. Biopsy of a soft-tissue lesion shows chronic inflammatory infiltrates with fibrotic stroma. The infiltrates consist of small and activated lymphoid cells and many infiltrates
