Metastatic Renal Cell Carcinoma in the Nasal Cavity and Mouth Floor / 대한이비인후과학회지

ABSTRACT

Renal cell carcinoma (RCC) has a high incidence of metastasis to any location in the body. This tumor metastasizes to the head and neck region in 15% of cases, whereas metastasis to the sinonasal area or to the mouth floor is rare. None of the cases of the RCC that are metastatic to both sites (sinonasal area and mouth floor) has been previously described. Recently, we experienced a case of metastatic RCC involving the nasal cavity and the mouth floor that were managed by local excision and postoperative radiotherapy. Because of its unpredictable clinical behavior, a long term follow-up is essential for early detection of recurrent or residual lesion of RCC.
