Within a few days postpartum, an abdominal computed tomography scan revealed a large left heterogeneous mass with mixed density and contrast enhancement and a small indeterminate liver lesion (Figures 1 A and B). Pathological analysis revealed chromophobe RCC, pT2bN0M0 with peri-nuclear halo and transitional cells (Figure 1 C).
