INTRODUCTION: Renal cell carcinoma (RCC) is often diagnosed as an incidental finding on imaging studies and about a fourth of patients have metastases by the time of diagnosis. RCC is known to metastasize widely but cutaneous metastases are considered uncommon and are rarely the presenting symptom of RCC. We present a case of RCC presenting with a tumor on the scalp.

CASE: A 65-year-old healthy man presented with a 9-month history of a growing mass on the scalp. Clinical examination revealed a pulsating, highly vascularized tumor that was excised. Histopathological findings were consistent with a metastasis from a renal cell carcinoma. Further investigations revealed a 13 cm kidney tumor with metastases to the lungs and mediastinum.

DISCUSSION: Cutaneous metastasis from RCC is uncommon and is rarely the initial symptom of RCC. The lesions often have a vascularized appearance and may be clinically confused with other vascular tumors. Skin metastasis is a sign of advanced disease and prognosis is poor.

CONCLUSION: An occult RCC may present with a skin lesion. Skin metastasis from RCC is an important differential diagnosis in tumors with a vascular appearance, especially in patients with a previous history of RCC.
