Papillary thyroid microcarcinoma with contralateral lymphatic skip metastasis and breast cancer: A case report

Figure 1 Ultrasound showed a nodule in the right thyroid lobe and an abnormal lymph node in left level V. A: A 7.8 mm × 7.4 mm heterogeneous hypoechoic nodule with obscure boundary and hyperechoic punctuations was observed in the middle and upper part of the right lobe of the thyroid gland; B: A hypoechogenic structure could be detected in level V, which was approximately 14.0 mm × 7.0 mm in size, with irregular shape, obscure boundary, heterogeneous echo, and unclear lymphatic hilus.

Figure 2 Hematoxylin and eosin staining of the right thyroid nodule and lymph node in left levels III and IV. A: Papillary thyroid microcarcinoma in the right thyroid lobe; B: Lymph node metastasis in left levels III and IV. Magnification: 800 ×.

Figure 3 Ultrasound for the abnormal lymph nodes in the left supraclavicular and level V areas. Several hypoechogenic structure were detected in the left supraclavicular and level V areas, one of which was approximately 10.1 mm × 6.5 mm in size with unclear lymphatic hilus.
