Intravenous urography showed that left pelvis, renal pelvis, and ureter were not developed (Figure 1E).
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.
