Renal metastasis from pancreatic adenocarcinoma: a rare case along with literature review.

Metastatic masses in the kidney are rare, and metastasis of pancreatic adenocarcinoma to the kidney is even rarer. A 58-year-old male patient with macroscopic hematuria presented to the emergency department. Abdominopelvic computed tomography revealed a lesion that was not visualized as a complete mass but instead appeared as a patch extending from the pelvis to the parenchyma. Biopsy indicated metastasis of pancreatic adenocarcinoma to the right kidney. These findings indicate that metastatic pancreatic adenocarcinoma should be considered in patients presenting with hematuria and findings of patch-like suspicious masses in the right kidney. After diagnosis is confirmed by prompt biopsy, chemotherapy should be initiated to prolong the patient's life. To the best of our knowledge, the present case is the first report of renal metastasis from pancreatic adenocarcinoma in a living patient.
