Cutaneous Acral Metastasis from Renal Cell Carcinoma-a Case Report.

Renal cell carcinomas are known to produce widespread and unpredictable metastasis due to their angioinvasive property. Cutaneous metastases from renal cell carcinomas are very rare, with a reported incidence of 1.3-3%. The sites of cutaneous metastasis from renal cell carcinomas, as per the available case reports, to the best of our knowledge, are shoulder, arm, nape of the neck, chest, face and scalp. We report a case of 63-year-old male, with renal clear cell carcinoma with lung metastasis who had cutaneous metastasis to the fingertip which was confirmed by histopathological examination. Apart from its rarity, this clinical case adds another site of renal cell carcinoma metastasis to the present literature. The skin metastasis represents a widely disseminated state of the disease with a very guarded prognosis and limited life span after its diagnosis.
