Abstract
A 60 year-old woman presenting with skin metastasis from renal carcinoma is reported.
Eleven years ago, she was diagnosed as right renal carcinoma, subsequently metastasis to the left kidney, lungs, brain, and pancreas were founded. She was treated then with immunotherapy, chemotherapy, and radiotherapy.
At her first visit to our hospital, she presented with a red firm skin nodule on the head. Histopathological studies revealed dermal nests consisting of atypical cells of non-cutaneous origin, similar to clear cell carcinoma of the kidney. She died about 10 months after the appearance of the skin tumor.
Skin metasitasis of the renal carcinoma is rare, and when it appears, the prognosis is often poor.
