case_images: The patient's CT images.. Notes: (A, B) Chest CT images showed a soft mass in the right upper lobe measuring 35x30x25 mm in size. (C, D) Lower abdominal enhanced CT showed a soft mass at the distal end of the ureter with uneven continuous enhancement.

case_images: The chest CT examination showed there was a soft mass in the right upper lobe (Figure 1A and B). As shown in Figure 1C and D, lower abdominal enhanced CT showed there was a soft mass at the distal end of the ureter with uneven continuous enhancement. Intravenous urography showed that left pelvis, renal pelvis, and ureter were not developed (Figure 1E).
case_images: Pathological characteristics demonstrated by H&E staining and immunohistochemical staining in the primary tumor.. Notes: The positive expression of TTF-1, CK7, Villin, and MUC1 was detected and the focal positive expression of Napsin A and CDX2. The negative expression of SPA, CK20, and MUC2 was detected.

case_images: As shown in Figure 2, the pathology showed that the tumor was diagnosis of adenocarcinoma with acinar predominant type and the pathologic stage was pT2N0M0.
case_images: Pathological characteristics demonstrated by H&E staining and immunohistochemical staining in the ureteral metastases tumor.. Notes: The positive expression of TTF-1, CK7, and Napsin A was detected and the partial positive expression of 34betaE12. The Ki-67 labeling index was90%. The negative expression of PSA, CK20, PAX-8, and P63 was detected.
