Fig. 1. Image and histopathological findings of patient 1. Longitudinal (A) and transverse (B, C) thyroid ultrasonographic images. Longitudinal image (A) shows a well-defined, 1.0 × 1.2 cm sized hypoechoic, microcalcified nodule in the right lobe and strap muscle invasion of the nodule is suspected. In addition, diffuse hypoechogenicity was noted adjacent to the thyroid nodule. Transverse image (B) reveals an ill-defined hypoechoic area in the subcapsular area of the left lobe, findings compatible with thyroiditis. Follow-up transverse image (C) shows recovery from thyroiditis. Tc-99m pertechnetate thyroid scan (D) shows marked decreased tracer uptake in both lobes of the thyroid. (E) (H&E stain, ×40) and (F) (H&E stain, ×200) show papillary carcinoma. Papillary carcinoma is associated with interstitial fibrosis that results from desmoplastic changes due to carcinoma. (G) (H&E stain, ×100) and (H) (H&E stain, ×200) show granulomatous inflammation and interstitial fibrosis with multinucleated giant cells, which suggest subacute thyroiditis.
