Solid bifocal pseudopapillary neoplasm of the pancreas: A case report.

INTRODUCTION

This neoplasm of the pancreas is an uncommon entity, with a frequency of 0.3-2.7% of all pancreatic tumors and even more so the finding of a synchronous lesion of the same histological lineage. For this reason, we report the atypical presentation of a SPNPs through a clinical case, review of the literature and a classification proposal, from the quantitative point of view.

CASE PRESENTATION

21-year-old patient, with incidental finding of two pancreatic tumors. Surgery included a pyloric preserving pancreatoduodenectomy with pancreatojejunostomy, distal pancreatectomy and central pancreas was preserved. The patient presents low output pancreatic fistula and nosocomial infection, treated with antibiotic therapy, being discharged 29 days after the intervention. Pathological and immunohistochemical analysis consistent with two SPNP.

DISCUSSION

Its diagnosis is confirmed with the histological study and two synchronic SPNP are a rare entity and for this, or multiple lesions, an attempt should be made of a conservative resection of the parenchyma to minimize pancreatic insufficiency in a frequently young population, and always look for R0 resection, due to its uncertain behavior.

CONCLUSION

Bifocal SPNP is rare and for this it is utility classify this entity -from the quantitative point of view- into unifocal, bifocal and multifocal for future medical research.
