Cutaneous Metastases and Long-Term Survival of a Patient With Clear Cell Renal Carcinoma.

The treatment landscape of metastatic renal cell carcinoma (mRCC) has changed in the last decade with improvements in overall survival. Overall survival ranges from 57 months in good-to-intermediate prognosis patients to 19 months in poor prognosis patients. The most frequent sites of metastasis are the lungs, bone, distant lymph nodes, liver, adrenal, and brain. Cutaneous metastases are rare and represent an end-stage disease with a worse prognosis. Studying long-term survivors of mRCC can help clinicians to identify potential predictors of response to targeted therapy and define the best treatment sequences in this setting. In this case, we report a 59-year-old man with a good mRCC prognosis who is alive 156 months after the diagnosis of mRCC, 108 months with cutaneous metastases. The patient underwent five treatment lines, with good tolerance and quality of life. This therapeutic sequence was based on new treatment options and new evidence concerning mRCC.
