We describe here a case of traumatic neuroma that developed in the pancreas head as a rare complication of pancreatic surgery for pseudocyst. A 50-year-old man presented with septic shock. The patient was a heavy drinker with history of operation for pancreatic pseudocyst 28 years ago. On the radiologic examinations, a poorly defined mass-like lesion was found in the uncinate process of pancreas, and it had features of chronic pancreatitis and a stricture of the distal common bile duct. Whipple's operation was performed due to the diagnosis of suspected pancreas head cancer. The pancreas revealed an ill-demarcated 4 cm sized firm mass with grayish white fibrotic cut surface in the head portion. On the microscopic examination, the mass was composed of haphazard proliferations of nerve fascicles in a fibrocollagenous matrix and this case was diagnosed as traumatic neuroma. Although traumatic neruoma is a rare cause of a pancreatic mass, it should be included as a differential diagnosis of pancreatic mass in patients with a history of pancreatic surgery.
