case_images: Computer tomography (CT) scan detected an enlarged transplanted kidney in the pelvic region on the left, and a bulky lesion of 8 cm x 7 cm was found in its parenchyma (Figure 1).
case_images: Histopathological slide of the tissue of the transplanted kidney subtotally replaced by the undifferentiated cells with small foci of recognizable clear cell renal cell carcinoma. There is a necrotic area in the upper right part of the image. Hematoxylin-eosin staining, x60

case_images: Further tumor regression was observed in the follow-up examinations, and complete regression of the tumor foci was registered 6 months after the operation (Figure 5).
