전이성 신세포암에서 수술 후 우연히 발견된 상악동 전이

Abstract

The classic presentation of renal cell carcinoma (pain, hematuria, and flank mass) occurs in a minority of patients and often is indicative of advanced disease. Common sites of metastatic renal cell carcinoma are lung, soft tissues, bone, and liver. Paranasal sinus is an unusual site for metastasis of renal cell carcinoma. One 73-year-old male presented to Soonchunhyang University Seoul Hospital with melena. Renal cell carcinoma with metastasis to duodenum was diagnosed by computed tomography (CT). He underwent right radical nephrectomy and Whipple's operation. Positron emission tomography/CT was performed postoperatively, and then metastasis to maxillary sinus was found by accident. He was treated with molecular targeted therapy (pazopanib hydrochloride 800 mg).
