신세포암의 십이지장 및 췌장 전이 1예

Abstract

Metastases to pancreas or duodenum are rarely occurring event. At autopsy, the pancreas has been found to be the site of metastases in approximately 2% of patients with malignant tumors that had originated most commonly from primary tumors located in breast, lung, and kidney. The natural history of renal cell carcinoma has been the subject of intensive study, yet its behavior remains unpredictable and poorly understood. Renal cell carcinoma may remain stable for long periods of time without growing or metastasizing, has the second highest spontaneous regression rate of all solid tumors, and metastases may develop many years after removal of the primary lesion. In patients with pancreatic mass, it is important to differentiate a secondary pancreatic tumor from primary one because satisfactory survival can be expected after surgical excision of secondary pancreatic tumor, especially when the primary tumor is renal cell carcinoma. Recently magnetic resonance image was reported to be useful in differentiating primary from secondary pancreatic tumor originated from kidney. We present a case of resectable solitary pancreatic and duodenal metastasis from renal cell carcinoma presenting as gastrointestinal bleed.
