Imaging showed a 9 cm right renal mass (Fig. 1C), multiple liver lesions concerning for metastases, and a right adnexal mass.
Retrograde pyelogram characterized by the classic "Goblet Sign" with filling defect (asterisks) indicative of ureteral obstruction from Case 1 (A). Hematoxylin and eosin-stained section revealing clusters of small palisading cells with hyperchromatic nuclei and crushed artifact (600 x , B). Cam 5.2 staining specific for neuroendocrine differentiation (600 x , C).

A classic "Goblet Sign" was identified on retrograde pyelography (Fig. 2A) and ureteroscopy revealed a large, friable, endophytic mass obliterating the lumen of the proximal ureter. Histologic evaluation revealed SCC characterized by positive immunohistochemical staining for CAM 5.2 (Fig. 2B, C).
