Abstract
Renal cell carcinoma can metastasize to any part of the body, and recurrences and/or metastases of this tumor have been reported even after a long interval from the initial therapy. We report two cases of renal cell carcinoma with metastasis to the head and neck region.
The patient was a 51-year-old male who had undergone left nephrectomy for renal cell carcinoma. Five years later, he presented with nasal obstruction and epistaxis. A solitary tumor in the epipharynx was surgically removed; histopathology of the resected specimen revealed the diagnosis of metastatic renal cell carcinoma.
The other patient was a 61-year-old male who had undergone left nephrectomy for a renal cell carcinoma. Twenty years later, he noticed a swelling in the right parotid gland region that was surgically removed; histopathological examination of the resected specimen revealed the diagnosis of metastatic renal cell carcinoma.
Until date, 18 cases of parotid gland metastasis have been reported in the literature, however, there have been no reports yet of epipharyngeal metastasis. Metastasis from renal cell carcinoma should be included in the differential diagnosis of head and neck tumors, even if a long time has elapsed after treatment of the primary lesion.
