M.A.Ennouhi Abstract: Metastasis of renal cell carcinoma is a common occurrence. However, it is very rare for these metastases to appear in unusual locations. In this case, we present the instance of a patient in his 70s who developed an ulcerating scalp tumor topped by a hemorrhagic crust, three years after the initial diagnosis of a stage T2b non-metastatic renal cell carcinoma. The primary tumor was treated with a nephrectomy and combined chemotherapy. Surgical removal of the skin tumor revealed, through pathology and immunohistochemistry, a metastatic clear renal cell carcinoma.
