Solitary jejunal metastasis from renal cell carcinoma presenting as small bowel obstruction 19 years after nephrectomy

Abstract

Metachronous metastatic disease may develop in up to 50% of patients with renal cell carcinoma (RCC) who have undergone a presumably curative radical nephrectomy. We describe a case of small bowel obstruction secondary to a solitary jejunal RCC metastasis affecting a 66-year-old man with a history of RCC, which was treated 19 years earlier by right radical nephrectomy. The patient underwent successful laparotomy and wide margin resection of the affected small bowel with end-to-end anastomosis. A subsequent staging CT revealed no other metastases. To our knowledge, only eight cases of isolated small bowel metastasis from RCC have been reported. Of these, only one previous report referred to a longer time interval to small bowel metastasis than our case. The case highlights that isolated bowel metastasis should be considered as a possible aetiology of small bowel obstruction, even in patients with a distant history of presumably curative cancer treatment.
