The histological examination revealed infiltrating urothelial carcinoma of the left renal pelvis with squamous differentiation and para-aortic lymph node metastasis (pT3N1M0) (Fig. 2A). Immunohistochemical staining using anti-G-CSF antibody demonstrated G-CSF secreting cells (Fig. 2B).
CT showed multiple lung metastasis 2 months after the operation. Red arrow heads show the metastasis of lungs.
