case_images: In September 2004, there was an 8 x 7 cm mass, and destruction of some of the cortical bone of the manubrium sterni had occurred, so a CT-guided percutaneous needle biopsy was performed. (Fig. 1) The mass was composed of clear tumor cells arranged in an alveolar configuration, and metastatic renal cell carcinoma was diagnosed histologically. (Fig. 2) We performed distant metastasis check up and check his physical function preparing for an operation.

case_images: Histological picture of the resected tumor specimen, showing that there were no carcinoma cells although granulation tissue, some bleeding and necrosis were present.

case_images: The entire resected tissue specimen was checked carefully, but no carcinoma cells were detected. (Fig. 3) We judged that a complete, spontaneous regression of metastatic renal cell carcinoma had taken place.
