Tumor sólido pseudopapilar de páncreas. Reporte de caso.

Introduction. Solid pseudopapillary neoplasia of the pancreas, also known as Frantz tumor, is a rare pathology, comprising less than 3% of pancreatic tumors, and the highest incidence is observed in young women between the second and third decades of life. Its etiology is unknown. The treatment of choice is surgical resection without lymphadenectomy when it is well located. Even when there is evidence of metastasis or local invasion, surgical management remains the treatment of choice. Clinical case. A 24-year-old woman presented with a palpable, painful abdominal mass of three weeks' duration. The computed tomography mentioned a tumor of pancreatic origin as a presumptive diagnosis. At laparotomy, a mass dependent on the body of the pancreas was found. Radical distal pancreatectomy with splenectomy and en bloc partial omentectomy was performed. Results. During the surgery there were no complications and until the sixth month of follow-up, the evolution was adequate and without tumor recurrence. Conclusions. In the presence of an abdominal mass, with pancreatic involvement documented by computed tomography, the diagnosis of solid pseudopapillary neoplasia of the pancreas, or Frantz tumor, should be considered, which must be treated surgically. Frantz tumor is a rare entity that is generally diagnosed incidentally or due to nonspecific symptoms in advanced stages. The diagnosis and management of this neoplasia represents a challenge and surgical resection continues to be the indicated treatment. [ABSTRACT FROM AUTHOR]
