Figure 2: Histological features of the initially resected thyroid tumor and the lymph node (a-c). (a) An encapsulated thyroid tumor featuring capsular invasion by tumor cells (H and E, ×20). (b) Histology of the papillary carcinoma (original thyroid tumor). Note the papillary structure of the tumor cells, the clarity of the nuclei, and the ground-glass presentation featuring occasional grooves (H and E, ×400). (c) Metastasis of the papillary carcinoma to a lymph node (H and E, ×40) (d) Histology of the lymph node resected 37 years after resection of the thyroid tumor. Note the presence of papillary carcinoma metastasis in the lymph node (H and E, ×40)
