ABSTRACT
ABSTRACT

BACKGROUND:

Solid pseudopapillary neoplasm of the pancreas is an uncommon pancreatic tumor, which is more frequent in young adult women. Familial adenomatous polyposis is a genetic condition associated with colorectal cancer that also increases the risk of developing other tumors as well.

AIM:

The aim of this study was to discuss the association of familial adenomatous polyposis with solid pseudopapillary neoplasm of the pancreas, which is very rare.

METHODS:

We report two cases of patients with familial adenomatous polyposis who developed solid pseudopapillary neoplasm of the pancreas of the pancreas and were submitted to laparoscopic pancreatic resections with splenic preservation (one male and one female).

RESULTS:

ß-catenin and Wnt signaling pathways have been found to play an important role in the tumorigenesis of solid pseudopapillary neoplasm of the pancreas, and their constitutive activation due to adenomatous polyposis coli gene inactivation in familial adenomatous polyposis may explain the relationship between familial adenomatous polyposis and solid pseudopapillary neoplasm of the pancreas.

CONCLUSION:

Colonic resection must be prioritized, and a minimally invasive approach is preferred to minimize the risk of developing desmoid tumor. Pancreatic resection usually does not require extensive lymphadenectomy for solid pseudopapillary neoplasm of the pancreas, and splenic preservation is feasible.
RESUMO
RESUMO RACIONAL A neoplasia sólida pseudopapilífera do pâncreas é um tumor pancreático incomum, mais frequente em mulheres jovens. A polipose adenomatosa familiar, por sua vez, é uma condição genética associada a câncer colorretal e que também aumenta o risco de desenvolvimento de outros tumores.

OBJETIVOS:

Discutir a associação entre polipose adenomatosa familiar e neoplasia sólida pseudopapilífera, que é bastante rara.

MÉTODOS:

Reportamos dois casos de pacientes com polipose adenomatosa familiar, um homem e uma mulher, que desenvolveram neoplasia sólida pseudopapilífera do pâncreas e foram submetidos a ressecção laparoscópica com preservação esplênica.

RESULTADOS:

As vias de sinalização da ß-catenina e Wnt tem um papel importante na tumorigênese da neoplasia sólida pseudopapilífera, e sua ativação constitutiva devido a inativação do gene adenomatous polyposis coli na polipose adenomatosa familiar pode explicar a relação entre polipose adenomatosa familiar e neoplasia sólida pseudopapilífera.

CONCLUSÕES:

A ressecção do cólon deve ser priorizada, com preferência pela abordagem minimamente invasiva para minimizar o risco de desenvolvimento de tumor desmoide. A ressecção pancreática geralmente não requer linfadenectomia extensa para neoplasia sólida pseudopapilífera, portanto, a preservação esplênica é factível.
