The mass was surrounded by multiple enhancing lesions and low-density nodules of different sizes with the largest one up to 4.3 cm in diameter (Figure 1A). In addition, a similar enhancing mass (3.8 x 3.7 cm) was also found in the Couinaud's S6 segment of the liver (Figure 1B). TTF-1 (thyroid transcription factor-1), and Ki-67 had positive expressions (Figure 2). Tissues of the liver mass, rectal wall nodules, and peritoneal nodules had the same nuclear features as those of the SO (Supplementary Figure S1).
HE staining [(A-C); original magnification x40, 100, and 400, respectively] and immunohistochemical staining [(D-G); original magnification x400] of samples taken from the tumor. HE staining (A,B) showing the presence of papillae. HE staining c showing irregular, enlarged, ground glass, and overlapping nuclei with grooves, and pseudoinclusions. (D), Galectin-3; (E), CK19; (F), TTF-1; (G), Ki-67.
