Ultrasonography, resected specimen, and histopathological appearance of the nodule of patient 4. a B-mode ultrasonography. Tumor: “nodule in nodule” appearance. Inner nodule: hypoechoic content, 42 × 23 × 22 mm. Outer nodule: isoechoic content, 79 × 32 × 60 mm. The boundary line between the nodules is well defined. b Power-Doppler ultrasonography. Blood signals: separate distribution. c Schema of thyroid ultrasound. Tumor: “nodule in nodule” appearance. d Sectional view of the resected thyroid specimen: inner tumor (i), outer tumor (ii). e Histopathological appearance of the inner tumor. HE stain. The microfollicular structure consisted of tumor cells. f MIB-1 staining of the inner tumor. Labeling index 10%. g Histopathological appearance of the outer tumor. HE stain. A macrofollicular structure was observed. h MIB-1 staining of the outer tumor. Labeling index <1%.
