Diagnosis and treatment of solid pseudopapillary tumor of the pancreas: A single center's experience.

Objective: The present study reviews the records of patients with solid pseudopapillary pancreas neoplasm (SPT).

Methods: A total of 13 patients diagnosed with SPT were included in the study. The criteria for SPT in the pathology specimens were the presence of cells with an oval round orthochromatic nucleus, with a thin chromatin structure and no nucleolus distinction, lined around a fibrovascular papilla in cystic areas.

Results: The study included 11 female and two male patients, with a mean age of 33.07 (range: 16-73) years. All operated patients underwent open surgery, with five undergoing a subtotal pancreatectomy and splenectomy; one a distal pancreatectomy and splenectomy; four a spleen-preserving distal pancreatectomy; and one a pancreaticoduodenectomy. None of the operated patients developed recurrence during the long-term follow-up. The mean follow-up time of operable patients was 69.18 (range: 22-97) months, and none had metastasis at follow-up. The mean follow-up time for the malignant SPT patients was 2.75 (1.5-4) months.

Conclusion: SPTs are rare pancreatic tumors encountered more frequently today due to advances in imaging methods and have a low potential of recurrence and a good prognosis.
