case_images: Diagnostic assessment: abdominal computer tomography (CT) scan revealed a heterogeneous right renal mass measuring 86 x76x 68 mm and arising from the upper and middle pole (Figure 1), with a lymph node of 8 mm diameter detected in the renal hilum as well as a multi lithiasis gallbladder (Figure 2).

case_images: The polypoid lesion of the gallbladder was identical to those of the renal tumor population, made up of large, plant-like cells with clear cytoplasm, adopting an acinar or solid architecture within a stroma rich in small vessels (Figure 3A, Figure 3B). Immunohistochemistry was positive for cytokeratin CK7, AMACR (a-Methylacyl Coenzyme A Racemase), cytokeratin (AE1/AE3), and vimentin (Figure 3C, Figure 3D).
