Fig. 3D. —61-year-old man with carcinoma of oral cavity. Comparison of reactively enlarged lymph node (A, B) and lymph node metastasis (C, D). However, contrast-enhanced color Doppler sonogram shows predominantly peripheral vessels (arrows) characteristic of metastasis. Thus, diagnosis was changed to lymph node metastasis, which was confirmed histologically. Arrowheads indicate lymph node.
