case_images: Imaging features were very typical of a primary bone tumor and thus, as tentative diagnosis chondrosarcoma was made by the reporting radiologist (Figure 1).

case_images: Biopsy specimen of the proximal left femur revealed a biphasic tumor composed of a cartilaginous component with abrupt transition into a noncartilaginous malignant mesenchymal component (Figure 2). During the further course of treatment, the suspicious condition in the right kidney, that had already been present during initial tumor staging prior to limb salvage surgery, was diagnosed as clear-cell renal cell carcinoma (Figure 2) and immediately subjected to nephrectomy.

case_images: However, her medical family history (Figure 3) revealed that her youngest brother started suffering from invasive medium- to-low differentiated urothelial carcinoma (Figure 4) of the bladder when he was 67-year-old. He died at age 69 of a fibroblastic osteosarcoma (Figure 4) located in his left femur.
