Metastatic Renal Cell Carcinoma: An Unusual Cause of Bleeding Pancreatic Mass.

Renal Cell Carcinoma metastasizing to pancreas is uncommon, occurring in 1-2% of cases; lung being the most common site. It is usually asymptomatic, or may present as abdominal pain, weight loss, pancreatitis or gastrointestinal bleeding. Herein, we present a case of 75-year-old male presented as intraabdominal bleeding to the Emergency Department. Contrast enhanced computed tomography with angiography of abdomen showed lobulated soft tissue mass in the uncinate process region, infiltrating into the distal third and proximal fourth part of duodenum. A clinico-radiological diagnosis of carcinoma head of pancreas infiltrating into duodenum was made and the patient underwent Whipple's operation. With past history of nephrectomy 3 years back, microscopy and the immunoprofile; a final diagnosis of clear cell renal cell carcinoma metastasizing to pancreas was given on histopathology. A high index of suspicion is required for patients with a history of RCC and they should be monitored lifelong for early detection of metastases and to improve survival.
