Colonic Metastasis of Renal Cell Carcinoma Two Years After Therapeutic Radical Nephrectomy a Case Report

Abstract Background: Renal Cell carcinoma usually presents metastasis at the diagnosis and the most common sites include lung, bones, liver, and brain in decreasing order. Metastasis to the large intestine is very uncommon and few cases are reported in the literature. Case Presentation: We present a case of post nephrectomy renal cell carcinoma who presented to our institution with signs of anemia and on further investigations found to be having metastatic lesions of renal cell carcinoma in the intestine, peritoneum, and abdominal wall. Conclusion: We hypothesize that due to recent advances in the treatment of renal cell carcinoma, the patient's survival rate increased and this leads to atypical presentations of the known diseases. Through this case report, we stress the importance of vigilant evaluation for intestinal metastasis when the patient presents with gastrointestinal bleeding and a history of renal cell carcinoma regardless of the time since nephrectomy.
