A Case of Metastatic Renal Cell Carcinoma in Submandibular Gland / 대한이비인후과학회지

ABSTRACT

Renal cell carcinoma takes up 85 per cent of primary malignant renal tumors. It frequently metastasizes to the adrenal gland, lung, bone, liver and nephrectomy site but rarely to the head and neck area. When metastasizes to head and neck area, it involves the gingiva, tongue, palate, parotid gland, uvula, mandible, and lip. When tumors are found in the salivary gland consisting of clear cells, it is impartant to carry out differential diagnosis of various primary tumors with clear cell and metastatic renal cell carcinoma. Patients' medical history, review of system, and pathologic findings would be helpful factors in the differential diagnosis. In this paper, we report on a case of renal cell carcinoma which had metastasized to the psubmandibular gland after a radical nephrectomy.
