  • Based on the results of our study, in combination with data from previous work (4), we suggest that a move of PDX1+ cells that have acquired Kras mutation toward ductal differentiation may provide the basis for pancreatic carcinogenesis, particularly in the conditions that do not actively promote inflammation.

  • Pancreatic panniculitis is a very rare complication associated with pancreatic disease, appearing in approximately 2 to 3% of all patients, most commonly those with acute or chronic pancreatitis, but also in patients with pancreatic carcinoma. (scitcentral.com)
  • PP occurs in 2-3% of all patients with pancreatic disease [3]. (scitcentral.com)

  • In every pediatric patient, cystic fibrosis has to be ruled out, since 10-15% of cystic fibrosis patients with pancreatic sufficiency (comprising 1-2% of all patients with cystic fibrosis) present clinically with recurrent attacks of acute pancreatitis. (medscape.com)
  • The increased detection of pancreatic cysts in asymptomatic patients has also led to an increase in the number of pancreatic biopsies and surgical interventions. (coek.info)
  • PP is usually described in association with benign pancreatic conditions, such as acute or chronic pancreatitis. (scitcentral.com)
  • The availability of tools to interrogate the transcriptome and proteome, such as expression profiling, have identified a substantial library of products that could aid in distinguishing a well-differentiated pancreatic carcinoma from a benign pancreatic lesion.2 Many of these proteins can be detected immunohistochemically and are thus available to the practicing pathologist (Table 2).3 Some of these markers have been validated on biopsy specimens as well.

  • Not only do these wrap pancreatic tumours in a dense, protective layer, they also foster complex relationships with the cancerous cells: some fibroblasts may fuel tumour growth, while other may help to contain its spread. (elifesciences.org)
  • The treatment is mainly directed towards the underlying pancreatic disease, which may result in regression of skin lesions. (scitcentral.com)
  • Skin lesions may precede the detection of the pancreatic disease by about 1-7 months and in cases of malignancies, it may be associated with increased risk of metastasis and/or associated with disease severity [6,9]. (scitcentral.com)
  • EUS is an essential tool in the differential diagnosis of CP with other pancreatic masses or cystic lesions. (medscape.com)
  • The pathogenesis is not fully understood, but it seems that the release of high amounts of pancreatic enzymes may lead to a focal necrosis of lipids and a concomitant inflammatory reaction. (scitcentral.com)
  • It is thought that the release of pancreatic enzymes (trypsin, lipase, amylase) in the bloodstream may be involved in increasing the vessel permeability with consequent neutral fat hydrolysis to form glycerol and free fatty acids, and finally producing fat necrosis and inflammatory response [2]. (scitcentral.com)
  • However, lipase levels are not the only factor implicated, as the relative frequency of pancreatitis with high serum lipase levels contrasts with the rarity of pancreatic panniculitis, and there are some PP cases in the literature that have been described with normal serum levels of all pancreatic enzymes [3], supporting the likely involvement of other unidentified factors in the causality of this entity.
