Metastasis of renal cell carcinoma to the neck; A case report

Metastasis of a renal cell carcinoma to head and neck regions is very rare. A 53-year-old woman presented with a large neck tumor on her left side. Several examinations revealed the mass to be metastasis of renal cell carcinoma. The patient also demonstrated complications of disseminated intravascular coagulation (DIG) about 3 weeks after the appearance of the neck tumor symptoms. A frozen section revealed the metastatic tumor to be a higher grade malignancy than the primary tumor. Thereafter the patient deteriorated rapidly. When lower cervical or supraclavicular adenopathy is found, the possibility of metastasis from peritoneal organs, including the kidney, should be considered.
