case_images: A PSMA-PET/CT scan was performed and was notable for a PET-avid right testicular mass (Figure 1).
case_images: (A) Scrotal ultrasound demonstrating long view of the medial right testicle with echogenic, heterogeneous, and well-circumscribed mass. (B) Doppler ultrasound demonstrating hypervascularity of the previously characterized mass.

case_images: Subsequent scrotal ultrasound showed a solid, hypervascular 8 mm x 7 mm x 7 mm mass in the right testicle concerning for primary germ cell tumor (Figure 2).
case_images: (A) Pushing border of well-circumscribed tumor in testis (4x); (B) Tumor shows classic well-vascularized nests of cells with clear cytoplasm (10x).

case_images: A right radical orchiectomy (Figure 3) was performed with final pathology demonstrating a metastatic clear cell RCC to the testis with lymphovascular invasion (Figure 4).
case_images: (A) Strong nuclear expression of PAX8 consistent with renal origin; (B) Strong membrane expression of CAIX supportive of clear cell RCC.
