A Case of Metastatic Renal Cell Carcinoma Invasion in External Auditory Canal / 대한이비인후과학회지

ABSTRACT

A renal cell carcinoma (RCC) is known for its high propensity for early metastasis. Among the metastatic cancers of the head and neck, RCC is the third most common disease after breast cancer and lung cancer. Head and neck metastasis of RCC occurs mainly in the thyroid gland (36.6%), nose and sinus (9.1%), and lesions in the ear canal and temporal bone are very rare. Although extremely rare, metastatic malignancy in the breast, lung, prostate, kidney to the external auditory canal have been reported in the literature. We report a case of metastatic RCC of the left external auditory canal in a 78-year-old male patient who had experienced multiple organ metastasis after nephrectomy due to renal cell carcinoma.
