case_images: The pathological results of the retroperitoneal mass showed a muscular tubular structure, with adenocarcinoma presented both inside and outside the tube wall (Figures 4A,B). The immunohistochemical (IHC) results showed that the cervical mass exhibited PAX8 (-), CK7(-), ER(-), PR(-), and P16(-) (Figures 4C-G). Retroperitoneal mass presented PAX8 focal(+), GATA3 focal(+), CDX2(+), CK20(+), CK7(-), and P63(-) (Figures 4H-M).
