Case report reveals isolated renal cell carcinoma metastasis to the esophagus 45 years after nephrectomy, indicating rarity of late recurrence.
Renal cell carcinoma (RCC) is a common malignancy, often discovered incidentally with abdominal imaging modalities. Metastasis of RCC to the esophagus is extremely rare. In this case, a patient presented with melena and dysphagia and was found to have an isolated metastasis of RCC in the proximal esophagus on endoscopy. He was previously treated for RCC 45 years ago, making this case the longest relapse of RCC documented in the literature to the best of our knowledge.
