[Cutaneous metastasis of renal cell carcinoma: A case report and review of the literature].
BACKGROUND
Renal cell carcinoma (RCC) accounts for 2-3% of adult solid malignancies. About 25-30% develop metastasis at the time of diagnosis and 60% corresponds to clear cell type.


METHODS
A 66-year-old man, with a personal history of left radical nephrectomy, presents with an asymptomatic skin tumor he noticed one month earlier. Histopathologic study reported metastatic cutaneous infiltration of clear cell carcinoma, suggestive of a primary renal carcinoma.


CONCLUSIONS
Cutaneous metastasis of RCC represents 6.0-6.8% of all cutaneous metastases. These patients have poor prognosis and, therefore, their treatment is palliative. It is essential to perform a complete periodic dermatologic examination for proper restaging and treatment.
