title: [A case report of small intestine metastasis from renal cell carcinoma].
abstract: A 71-year-old man underwent left nephrectomy for metastasis from renal cell carcinoma (RCC) of the small intestine. In spite of post-operative therapy (interferon-alpha or interleukin-2), multiple lung metastases and intestinal hemorrhage by metastatic tumor of small intestine appeared 9 years after the operation. To control the bleeding from the small intestine, the small intestine was partially excised and the histopathological diagnosis was metastasis of RCC. He died 10 months later because of disease progression. Metastasis of RCC to the small intestine is rare. To our knowledge, this is the 40th case of small intestinal metastasis from RCC reported in the literature.
