Pancreatic Neuroendocrine Tumors
Surgical Pathology Clinics, 2016Pancreatic neuroendocrine neoplasms include well-differentiated pancreatic neuroendocrine tumors (PanNETs) and neuroendocrine carcinomas (NECs) with well-differentiated PanNETs accounting for most cases. Other pancreatic primaries and metastatic carcinomas from other sites can mimic pancreatic neuroendocrine neoplasms.

AbstractRapid tumor lysis may produce acute complications including systemic metabolic disturbances and hemorrhage in sites involved by tumor. We have observed two cases of acute pancreatitis induced by the lysis of lymphoma that involved the pancreas. This previously unreported cause of pancreatitis must be added to the list of potential complications

Pancreatic hepatocellular tumor
Pancreatology, 2005Hepatocellular differentiation of pancreatic cells has been observed under certain conditions in several species, including humans. Their cell of origin and biology has remained controversial. Generally, these lesions have been considered a degenerative process.

Pancreatic neuroendocrine tumors
Current Problems in Surgery, 2013Pancreatic neuroendocrine tumors (PNETs) have an incidence of approximately 1 per 100,000 individuals per year, and account for 1–2% of all pancreatic tumors. The annual incidence in the United States is about 3.65 per 100,000 population. Although they may manifest at any age, they most often occur in the fourth to sixth decades of life. Most PNETs are

In this review the current state of our understanding of endocrine tumors of the pancreas is considered. It is based on the experience with a series of 365 tumors. The first part of the article focuses on origin and classification, markers, frequency, criteria of malignancy as well as general structural features of the pancreatic endocrine tumors.

Pediatric Surgery International, 1996
Pancreatic tumors rarely present in childhood. Diagnostic difficulty and inappropriate treatment may occur due to the variable clinical appearance of the illness. A 26-year audit (1968-1994) at this institution showed five patients ranging in age from 5 to 14 years who were operated upon for pancreatic tumors, four of which were malignant. In two cases

Pancreatic Tumor Microenvironment
2020The pancreatic ductal adenocarcinoma (PDAC) microenvironment is a diverse and complex milieu of immune, stromal, and tumor cells and is characterized by a dense stroma, which mediates the interaction between the tumor and the immune system within the tumor microenvironment (TME).

Cystic lesions of the pancreas are increasingly being recognized due to the widespread use of cross-sectional imaging, and include a large variety of lesions with different etiology and biology, each requiring a different management strategy [1]–[5].

Pancreatic neuroendocrine tumors
Indian Journal of Gastroenterology, 2012Pancreatic neuroendocrine tumors (pancreatic NETs) are rare, low- to intermediate-grade neoplasms thought to arise from the pancreatic islets. Recent advances in pathology and our understanding of the biological behavior of this group of tumors has resulted in changes in their nomenclature and how we treat them.
