case_images: MRI dynamics of liver tumor growth. (A) Heterogeneous mass with clear irregular contours of 5x3 cm in the lower part of the 6th liver segment detected in 2021. (B) Growth dynamics of the liver tumor up to 7x5 cm in 2022.

case_images: The imaging characteristics suggested a vascular origin, such as hemangioma (Figure 1).
case_images: Tumor sections with glandular structures, cystic expansion, abundance of eosinophilic amorphous material in the lumen (H&E). (A,B) There is diffuse marked membranous cytoplasmic expression of cytokeratin 7 (C) and moderate focal membranous cytoplasmic expression of cytokeratin 19 (D) in the tumor cells; proliferative expression index by Ki-67 (E); we detected granular cytoplasmic expression of TTF1 in the surrounding normal liver tissue, in the absence of primary thyroid cancer-specific nuclear expression in the tumor (F).
