Review Case Reports
[Renal cell carcinoma detected by metastasis to the frontal sinus: a case report].
A 58-year-old man was admitted with a swelling in the frontal region. Computerized tomography scan, magnetic resonance imaging and angiography revealed a tumor in the right frontal sinus. ⋯ Since there were no other systemic metastases, right nephrectomy was performed. Pathologically, the renal tumor was clear cell subtype renal cell carcinoma and had the same histology as the frontal sinus tumor.
