Solid pseudopapillary tumor (SPT) of the pancreas is one of the most uncommon histotypes of all exocrine pancreatic neoplasms. Disorganization of E-cadherin and β-catenin mutations, two key components of the Wnt signal transduction pathway, has been implicated in the development of SPT, but not other pancreatic tumors. Loss of E-cadherin/β-catenin proteins and tyrosine phosphorylation of E-cadherin/β-catenin have been postulated in cervical carcinogenesis and cancer invasion. A 38-year-old married woman, who had undergone brachytherapy, radiotherapy and chemotherapy for cervical cancer in Philippines in 2011, was admitted to our hospital after follow-up CT scan of abdomen in 2012 revealed a lesion in the tail of pancreas. The patient underwent distal pancreatectomy and splenectomy. The pathological diagnosis was SPT of pancreas. We suspect that the concurrent SPT pancreas and cervical cancer in this woman were triggered by a primary insult, a process in which E-cadherin/β-catenin/Wnt-signaling pathway played important roles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
