Solid pseudopapillary tumors of the pancreas in young women: Case report

INTRODUCTION AND IMPORTANCE

Solid pseudopapillary tumor of the pancreas (SPTP) is a rare tumor of the exocrine pancreas, with undetermined etiopathogeny, which most often affects young women. The clinical and physical signs are non-specific and despite the progress of complementary examinations, Confirmation is usually anatomopathological. Surgical resection is the only curative treatment.

CASE PRESENTATION

We report the case of a 17-year-old girl, consulted for a left hypochondrium mass which imaging concluded to be a corporal-caudal tumor mass of the pancreas for which a complete surgical excision was performed and whose anatomopathological study confirmed a pseudo-papillary and solid tumor of the pancreas. The positive diagnosis of SPTP remains difficult and is usually made on pathological analysis with immunohistochemical study.

DISCUSSION

Solid pseudopapillary tumor of the pancreas is a rare anatomic-clinical entity, first described by Frantz in 1959. The clinical manifestations of SPTP are not specific. Biologically, no signs are predictive of SPTP and imaging usually shows a well encapsulated mass with both solid and cystic components. The curative treatment of SPTP is exclusively surgical and consists of a complete removal of the tumor with its capsule because of its degenerative potential SPTP has a good prognosis with a recurrence rate of 10-15% and 95% survival at 5 years.

CONCLUSION

Solid pseudopapillary tumor of the pancreas is a rare tumor of the exocrine pancreas. Its evolution is slow. Preoperative diagnosis remains difficult despite the progress of complementary examinations. Surgical resection is the only curative treatment. Its prognosis remains excellent.

Hepatic metastasis in Frantz's tumor: A case report

•

This is a borderline tumor with indolent biological behavior.

•

There are still multiple poorly understood factors that can dictate its malignant transformation and prognosis.

•

Here, a rare tumor whose age and survival are tangent the literature reports describe.

•

There is a need for a long and rigorous segment to identify possible long-term metastases.

Introduction

Frantz’s Tumor or Solid Pseudopapillary Neoplasm (SPN) is rare with a solid-cystic pattern, and most common in young women.

Presentation of case

This study based on guidelines for case reports (SCARE) reports a case of SPN in a teenager aged 13 years at the diagnosis time, attended at a teaching public hospital in Brazil, which evolved into liver metastases. Clinical, laboratory, therapeutic and imaging data were collected from the physical chart and analyzed in light of current publications on the topic. The first consultation occurred in January 2012, where weight loss, fever, vomiting, left-sided hypochondrium and epigastric pain were reported. Imaging exams evidenced an expansive heterogeneous process in the pancreatic tail; however, laboratory exams and tumor markers did not present alteration in relation to reference values. In March of 2012, she underwent caudal body pancreatectomy, splenectomy, segmental colectomy and colo-coloanastomosis as a function of the intraoperative findings. After 63 months, right-sided hepatectomy was performed to resect metastases. Currently, she is undergoing outpatient monitoring, without complaint or alterations in imaging and laboratory exams, totaling 100 months of global survival.

Discussion

This is an interesting case report of a rare tumor, in so far as without any adjuvant chemotherapies, an 8-year long survival time could be achieved in this particular type of tumor despite initially large tumor expansion and later liver metastases.

Conclusion

Additional epidemiological studies, molecular and clinical trials are required to increase knowledge on SPN.
