A Case of Renal Cell Carcinoma Metastatic to the Scalp / 대한피부과학회지

ABSTRACT

Cutaneous metastasis from renal cell carcinoma is unusual and have been reported infrequently. We report a case of metastatic renal cell carcinoma in a 33-year-old man who presented with a 3.5X2.0 cm-sized round, brightly red colored nodule on the scalp for 1 month. A skin biopsy revealed the typical clear cell adenocarcinoma with clear cytoplasm and oval hyperchromatic nuclei arranged in glandular pattern consistent with metastatic renal cell carcinoma. In most instances, once cutaneous involvement is manifested the disease is widespread and has a poor prognosis. But, our case presented only a single cutaneous nodule, and workup showed no evidence of further metastasis for 1 year.
