Abstract

Cutaneous metastasis from renal cell carcinoma is unusual. Cutaneous metastasis is considered as a late manifestation. On rare case it may represent the initial presentation of renal cell carcinoma.
We report a case of 57-year-old male renal cell carcinoma patient with skin metastasis. He noticed his cutaneous lesion on his scalp about 7 months before visiting our hospital. The lesion enlarged and he gradually felt abdominal pain and dyspnea. From the result of pathological examination and abdominal ultrasonography, the metastasis from renal cell carcinoma was suggested. The disease progressed rapidly and he died of respiratory failure 11 days after first visiting our hospital.
We review the case reports about renal cell carcinoma patients with skin metastases in recent 10 years in Japan.
