A Case of Solid Pseudopapillary Tumor of the Pancreas

We report a rare case of solid pseudopapillary neoplasm in a 24-year-old woman, who presented with progressively worsening left epigastric and right lower quadrant abdominal pain for several weeks. A CT scan showed a mass in the tail of the pancreas that extended to the hilum of the spleen. Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) and immunohistochemical analysis exhibited findings pathognomonic for solid pseudopapillary neoplasm. The patient underwent distal pancreatectomy and splenectomy. Post-surgical biopsy confirmed the FNA findings, with the tumor confined to the pancreas and no extension to nearby structures. The patient did not require any other adjuvant therapy. She was asymptomatic at the one-month follow-up and showed no signs of disease. We discuss the unique circumstances of this case and highlight the importance of differentiating this tumor from other pancreatic neoplasms.
