Background: Solid pseudopapillary tumors are rare pancreatic tumors. Accurate preoperative diagnosis helps in planning of the surgery. Aim: This study was to evaluate accuracy of endoscopic ultrasound-guided fine needle aspiration and immunohistochemistry in diagnosing solid pseudopapillary tumors. Materials and Methods: A retrospective review was performed by reviewing medical records to identify patients treated for solid pseudopapillary tumors over a 5-year period. Patients who were noted to have pancreatic lesions by computer tomography abdomen underwent endoscopic ultrasound. Fine needle aspiration was obtained from each of these lesions and subjected to immunohistochemistry. Results: Five patients were identified. Endoscopic ultrasound was able to identify the pancreatic lesions in all five patients noted in computer tomography abdomen. Solid pseudopapillary tumors were diagnosed by immunohistochemistry. All five patients underwent surgery and the resected lesions confirmed solid pseudopapillary tumors in 80% patients. Conclusion: Endoscopic ultrasound-guided fine needle aspiration has a higher degree of accuracy in diagnosing solid pseudopapillary tumors.
