Papillary renal cell carcinoma presenting as nodal metastases to the neck.

Renal cell carcinoma, in a high percentage of patients, metastasizes early, sometimes mimicking other lesions. We present a case of an asymptomatic papillary renal cell carcinoma that presented neck metastases as the initial manifestation. The laterocervical and supraclavicular masses were considered consistent with nodal metastases from a thyroid nodule. A hemithyroidectomy was performed before the renal tumor was diagnosed. Then the patient underwent a left-side radical nefrectomy. We discuss the unpredictability of the clinical course of renal cell carcinoma.
