An 82-year-old man underwent a left upper lobectomy for a solitary tumor on suspicion of lung cancer. Histopathologic findings of the resected specimen showed clear cell renal cell carcinoma, which was diagnosed as a metastasis from kidney cancer concealed for 31 years after nephrectomy.
The Ki-67 labeling index of the metastatic tumor was high (36 1%) A few cases of recurrent renal cell carcinoma after a long interval from initial diagnosis have been seen However, pulmonary metastasectomy more than 30 years after radical nephrectomy for renal cell carcinoma has not been reported This remarkable case provides new and valuable clinical insights into metastatic renal cell carcinoma
