Frantz tumor: Case reports

Introduction: Frantz tumor or Solid Pseudopapillary Neoplasm are rare neoplasms that represent between 0,2-2,7 % of exocrine pancreatic neoplasms. It was first described by Virginia K. Frantz in 1959, but it was included in the World Health Organization (WHO) classification of pancreatic tumors in 1996 as a “pseudopapillary tumor” of the pancreas. Of unknown etiology, its incidence is observed in young women; Clinically it manifests with slow growth of a solid abdominal mass accompanied or not by abdominal pain. There has been a gradual increase in the incidence of this tumor in the last two decades, probably due to the greater frequency of the use of cross-sectional images in the evaluation of abdominal symptoms. Its degree of malignancy is low and complete resection allows the patient a favorable evolution and prognosis. Materials and Methods: a retrospective observational bibliography review of patients with PNS operated on from October 2016 to December 2022 was carried out. Results: the patients operated on for Frantz tumor analyzed in the study did not have recurrences and/or metastases. Conclusion: pseudopapillary neoplasia of the pancreas (Frantz's tumor) should be considered in the differential diagnosis of pancreatic tumors, especially in young women, since surgical treatment has a good prognosis even if the tumors are large.
