Abstract

Solid pseudopapillary tumor (SPT) is known to be cured in more than 95% of patients after surgery. However, it is reported that 7% of this tumor can recur after resection, and continued surveillance is needed after surgery for SPT. In this case report, a pancreatic mass which had been detected during a routine health checkup was followed up and surgical resection (distal pancreatectomy) was performed due to an increase in size. Postoperative pathology revealed synchronous SPT and neuroendocrine tumor (NET). At twelve months after surgery, a recurrence of the mass in the head of the remnant pancreas was noted and further surgical resection (total pancreatectomy) was performed. Postoperative pathology confirmed the diagnosis of malignant SPT. To date, there are only a few reports of the synchronous SPT and NET, and there are no reports in Korea. Therefore, we report a case of the synchronous SPT and nonfunctional NET diagnosed after surgery.
