Background:
Spontaneous regression of metastatic renal cell carcinoma is rarely observed.
Case Presentation:
Metastatic renal cell carcinoma was identified in a 70-year-old male using computed tomography-guided percutaneous needle biopsy. Two months after the diagnosis, a partial resection of the sternal bone was performed. Pathological examination revealed granulated tissue with bleeding and necrosis but no carcinogenic cells.
Conclusion:
We report a pathologically identified case in which a sternal bone metastasis that was noticed two years after radical nephrectomy regressed completely and spontaneously.
