title: Recurrent invasive intraductal papillary mucinous carcinoma of the pancreas mimicking pott disease: review of the literature.
abstract: Specific information regarding intraductal papillary mucinous neoplasm (IPMN) recurrence is limited because most series are small and the follow-up interval is short. We report an unusual case of cancer recurrence in an 86-year-old woman who had undergone a pancreaticoduodenectomy for a large IPMN in the head of the pancreas. Final pathological evaluation of the resected pancreas found a component of in situ and invasive ductal adenocarcinoma without lymph node involvement. The patient did not receive postoperative chemotherapy and was monitored with transaxial imaging at regular intervals. Nine years later, the patient developed a retroperitoneal psoas abscess that was misdiagnosed as tuberculous spondylitis (Pott disease) but was proven to be recurrent mucinous adenocarcinoma of pancreatic origin. In our review of published reports in patients who underwent resection of IPMN, we found a combined mean recurrence rate of approximately 20%.
