Abstract

|
Solid pseudopapillary tumors of the pancreas are rare and typically occur in young women. Compared with pancreatic adenocarcinoma, solid pseudopapillary tumors are characterized by notable indolent biological behavior associated with a favorable prognosis. Despite their large size, these tumors rarely metastasize. Even in cases of hepatic metastasis, most lesions are usually solitary in distribution and are amenable to resection. We report a case of a 55-year-old man with a small solid pseudopapillary tumor (≤3-cm diameter) mimicking a pancreatic adenocarcinoma, with multiple hepatic metastases. The diagnosis was confirmed by endoscopic ultrasound-guided fine-needle biopsy using a 22-G core needle. Unfortunately, rapid tumor progression led to patient mortality 5 months after diagnosis. To our knowledge, this is the first case report that describes a small solid pseudopapillary tumor of the pancreas with multiple hepatic metastasis and poor prognosis in a patient who was diagnosed with this condition at the time of initial diagnosis.
