Late Presentation of Metastatic Renal Cell Carcinoma as a Bleeding Duodenal Mass / 대한내과학회지

ABSTRACT

Gastrointestinal metastasis of a renal cell carcinoma is very rare, and the clinical course of the disease ranges from months to several decades. We experienced a case of solitary duodenal metastasis about 22 years after a right nephrectomy for clear-cell type renal cell carcinoma in a 77-year-old man who complained of melena. This case is the longest reported time interval between surgical nephrectomy to presentation with a duodenal metastasis. Patients usually present with recurrence within a year after radical nephrectomy but can present after many years, warranting lifelong surveillance.
