Abstract
Solid pseudopapillary tumor (SPT) is an uncommon neoplasm of the pancreas. A rare case of spontaneous rupture of SPT is reported. A 13-year-old female felt acute abdominal pain without blunt abdominal trauma. Enhanced computed tomography (CT) revealed a tumor in the pancreas tail with fluid collection around it. The tumor was diagnosed as SPT with hemoperitoneum associated with spontaneous rupture. The bleeding was stopped conservatively and she was referred for surgery at three months after the rupture. At that time, CT revealed a tumor 4 cm in diameter, which protruded from pancreas tail without distant metastases. Since peritoneal dissemination was not seen on intraoperative exploration, laparoscopic enucleation was performed. Pathologically, the tumor was diagnosed as SPT with rupture of the capsule of tumor, and complete resection was confirmed. The patient has been followed up for two years, and she is alive without recurrence.
