Section of the tumor at the superior renal pelvis, showing low-grade papillary transitional cell carcinoma, consisting of branching papillary fronds with fibrovascular cores ((a) low-power 4x objective). Note that tumor is confined to epithelium, with no invasion into the lamina propria or beyond. High-power view ((b) 40x objective) shows an orderly appearance of neoplastic cells with only mild nuclear pleomorphism and inconspicuous nucleoli.
