Metastatic renal cell carcinoma to stomach.

Metastatic tumors to the stomach are distinctly unusual. Rarer still is renal cell carcinoma metastatic to the stomach following radical excision of the primary tumor several years previously. During evaluation for an upper gastrointestinal hemorrhage, a patient was found to have a large antral mass. Endoscopic biopsy revealed renal cell carcinoma. At celiotomy the tumor was found to have penetrated through to the liver capsule. An antrectomy and wedge resection of the left lobe of the liver was performed. There was no evidence of further metastatic disease. This is the first report of such a patient resected for cure, and emphasizes the unique biology of this tumor in its potential for late, solitary metastasis and surgical resectability.
