Late solitary pancreatic metastasis from renal cell carcinoma diagnosed on endoscopic ultrasound-guided fine-needle aspiration biopsy: A rare case report

Abstract

Metastasis of renal cell carcinoma to the pancreas is a rare neoplasm accounting for 0.25%–3% of all pancreatic tumors and most cases arise from renal cell carcinoma. Symptomatic patients usually present with obstructive jaundice, abdominal pain, or gastrointestinal (GI) bleeding . The diagnosis usually occurs in asymptomatic patients during follow-up for renal cell carcinoma. It usually befalls slowly from 2 to 18 years after the onset of the primary tumor of the kidney. We report a case of a 58-year-old male patient who presented to the hospital with weight loss, anorexia, and elevated blood glucose and found to have a large tumor in the head of the pancreas, diagnosed on contrast-enhanced computed tomography. Patient underwent left radical nephrectomy 10 years ago for renal cell carcinoma.
