==Overview==
[[Pancreatic cancer]] must be differentiated from other [[Pancreas|pancreatic]] pathologies such as [[chronic pancreatitis]], [[autoimmune pancreatitis]], [[pancreatic pseudocyst]], and neuroendocrine tumors of the pancreas. Pathologies of the [[bile duct]] and [[duodenum]] such as [[Choledocholithiasis]], [[Gallstone disease|gallstones]] ([[Gallstone disease|Cholelithiasis]]), [[Bile duct cyst|Choledochal Cysts]], [[Cholangiocarcinoma]], [[Bile duct]] [[Stenosis|strictures]] and [[Ampulla of Vater|ampullary]] cancer should be differentiated from [[pancreatic cancer]] based on [[imaging]] and [[biopsy]] findings. [[Metastasis]] from different sites and [[vascular]] causes such as [[Abdominal aortic aneurysm|abdominal aortic aneurysms]] may also mimic [[pancreatic cancer]].
[[Pancreatic cancer]] must be distinguished from other pancreatobiliary pathologies that cause [[abdominal pain]] and [[jaundice]] such as acute [[Pus|suppurative]] [[cholangitis]], [[Cholecystitis|acute cholecystitis]], [[Gallstone disease|cholelithiasis]], [[chronic pancreatitis]], [[primary biliary cirrhosis]] and [[primary sclerosing cholangitis]]. [[Pancreatic cancer]] must also be differentiated from other [[Pancreas|pancreatic]] [[Pathological|pathologies]] such as  [[autoimmune pancreatitis]], [[pancreatic pseudocyst]], and [[neuroendocrine tumors]] of the pancreas. [[Pathological|Pathologies]] of the [[bile duct]] and [[duodenum]] such as [[Choledocholithiasis]], [[Gallstone disease|gallstones]] ([[Gallstone disease|cholelithiasis]]), [[Bile duct cyst|choledochal cysts]], [[Cholangiocarcinoma]], [[Bile duct]] [[Stenosis|strictures]] and [[Ampulla of Vater|ampullary]] cancer should be differentiated from [[pancreatic cancer]] based on [[imaging]] and [[biopsy]] findings.

==Differentiating Pancreatic Cancer from other Diseases==
==Differentiating Pancreatic Cancer from other Diseases==


The differentials for [[pancreatic cancer]] mainly involve pathologies of the [[pancreas]], [[bile duct]], [[duodenum]], lymphovascular tissue or [[metastasis]] from other sites. It is difficult to differentiate pancreatic cancer from other neoplasms as they all present with non specific constitutional symptoms. Hence, differentiation is primarily based on investigations:<ref name="pmid29029521">{{cite journal |vauthors=He XK, Ding Y, Sun LM |title=Contrast-enhanced endoscopic ultrasound for differential diagnosis of pancreatic cancer: an updated meta-analysis |journal=Oncotarget |volume=8 |issue=39 |pages=66392–66401 |year=2017 |pmid=29029521 |pmc=5630421 |doi=10.18632/oncotarget.18915 |url=}}</ref><ref name="pmid29022085">{{cite journal |vauthors=Steinman J, Zaheer A, Kluger MD, Remotti H, Hecht EM |title=Rare pancreatic tumors |journal=Abdom Radiol (NY) |volume= |issue= |pages= |year=2017 |pmid=29022085 |doi=10.1007/s00261-017-1342-x |url=}}</ref><ref name="pmid28700485">{{cite journal |vauthors=Ran L, Zhao W, Zhao Y, Bu H |title=Value of contrast-enhanced ultrasound in differential diagnosis of solid lesions of pancreas (SLP): A systematic review and a meta-analysis |journal=Medicine (Baltimore) |volume=96 |issue=28 |pages=e7463 |year=2017 |pmid=28700485 |pmc=5515757 |doi=10.1097/MD.0000000000007463 |url=}}</ref><ref name="pmid28216481">{{cite journal |vauthors=Kołodziejczyk E, Wejnarska K, Oracz G |title=Autoimmune pancreatitis in the paediatric population - review of the literature and own experience |journal=Dev Period Med |volume=20 |issue=4 |pages=279–286 |year=2016 |pmid=28216481 |doi= |url=}}</ref><ref name="pmid28197876">{{cite journal |vauthors=Zhu L, Xue HD, Liu W, Wang X, Sui X, Wang Q, Zhang D, Li P, Jin ZY |title=Enhancing pancreatic mass with normal serum CA19-9: key MDCT features to characterize pancreatic neuroendocrine tumours from its mimics |journal=Radiol Med |volume=122 |issue=5 |pages=337–344 |year=2017 |pmid=28197876 |doi=10.1007/s11547-017-0734-x |url=}}</ref><ref name="pmid28154274">{{cite journal |vauthors=Sano I, Katanuma A, Yane K, Kin T, Nagai K, Yamazaki H, Koga H, Kitagawa K, Yokoyama K, Ikarashi S, Takahashi K, Maguchi H, Omori Y, Shinohara T |title=Pancreatic Metastasis from Rectal Cancer that was Diagnosed by Endoscopic Ultrasonography-guided Fine Needle Aspiration (EUS-FNA) |journal=Intern.

===Differentiating Pancreatic Carcinoma on the basis of involved Organ===
The differentials for [[pancreatic cancer]] mainly involve pathologies of the [[pancreas]], [[bile duct]], [[duodenum]], lymphovascular tissue or [[metastasis]] from other sites. It is difficult to differentiate pancreatic cancer from other [[neoplasms]] as they all present with non specific constitutional [[symptoms]]. Hence, differentiation is primarily based on anatomic location:<ref name="pmid29029521">{{cite journal |vauthors=He XK, Ding Y, Sun LM |title=Contrast-enhanced endoscopic ultrasound for differential diagnosis of pancreatic cancer: an updated meta-analysis |journal=Oncotarget |volume=8 |issue=39 |pages=66392–66401 |year=2017 |pmid=29029521 |pmc=5630421 |doi=10.18632/oncotarget.18915 |url=}}</ref><ref name="pmid29022085">{{cite journal |vauthors=Steinman J, Zaheer A, Kluger MD, Remotti H, Hecht EM |title=Rare pancreatic tumors |journal=Abdom Radiol (NY) |volume= |issue= |pages= |year=2017 |pmid=29022085 |doi=10.1007/s00261-017-1342-x |url=}}</ref><ref name="pmid28700485">{{cite journal |vauthors=Ran L, Zhao W, Zhao Y, Bu H |title=Value of contrast-enhanced ultrasound in differential diagnosis of solid lesions of pancreas (SLP): A systematic review and a meta-analysis |journal=Medicine (Baltimore) |volume=96 |issue=28 |pages=e7463 |year=2017 |pmid=28700485 |pmc=5515757 |doi=10.1097/MD.0000000000007463 |url=}}</ref><ref name="pmid28216481">{{cite journal |vauthors=Kołodziejczyk E, Wejnarska K, Oracz G |title=Autoimmune pancreatitis in the paediatric population - review of the literature and own experience |journal=Dev Period Med |volume=20 |issue=4 |pages=279–286 |year=2016 |pmid=28216481 |doi= |url=}}</ref><ref name="pmid28197876">{{cite journal |vauthors=Zhu L, Xue HD, Liu W, Wang X, Sui X, Wang Q, Zhang D, Li P, Jin ZY |title=Enhancing pancreatic mass with normal serum CA19-9: key MDCT features to characterize pancreatic neuroendocrine tumours from its mimics |journal=Radiol Med |volume=122 |issue=5 |pages=337–344 |year=2017 |pmid=28197876 |doi=10.1007/s11547-017-0734-x |url=}}</ref><ref name="pmid28154274">{{cite journal |vauthors=Sano I, Katanuma A, Yane K, Kin T, Nagai K, Yamazaki H, Koga H, Kitagawa K, Yokoyama K, Ikarashi S, Takahashi K, Maguchi H, Omori Y, Shinohara T |title=Pancreatic Metastasis from Rectal Cancer that was Diagnosed by Endoscopic Ultrasonography-guided Fine Needle Aspiration (EUS-FNA) |journal=Intern.

Overview

Pancreatic cancer must be distinguished from other pancreatobiliary pathologies that cause abdominal pain and jaundice such as acute suppurative cholangitis, acute cholecystitis, cholelithiasis, chronic pancreatitis, primary biliary cirrhosis and primary sclerosing cholangitis. Pancreatic cancer must also be differentiated from other pancreatic pathologies such as autoimmune pancreatitis, pancreatic pseudocyst, and neuroendocrine tumors of the pancreas. Pathologies of the bile duct and duodenum such as Choledocholithiasis, gallstones (cholelithiasis), choledochal cysts, Cholangiocarcinoma, Bile duct strictures and ampullary cancer should be differentiated from pancreatic cancer based on imaging and biopsy findings. Metastasis from different sites and vascular causes such as abdominal aortic aneurysms may also mimic pancreatic cancer.

Differentiating Pancreatic Cancer from other Diseases

Pancreatic cancer may also be distinguished from other causes of abdominal pain and jaundice as depicted in the table below:

Differentials based on weight loss, nausea, vomiting, diarrhea, fatigue and abdominal pain

Pancreatic carcinoma should be differentiated from other diseases presenting with weight loss, nausea, vomiting, diarrhea, fatigue and abdominal pain. The differentials include the following:

Disease Clinical manifestations Diagnosis Comments

Abdominal Pain Fever Rigors and chills Nausea or vomiting Jaundice Constipation Diarrhea Weight loss GI bleeding Hypo-

Differentiating Pancreatic Carcinoma on the basis of involved Organ

The differentials for pancreatic cancer mainly involve pathologies of the pancreas, bile duct, duodenum, lymphovascular tissue or metastasis from other sites. It is difficult to differentiate pancreatic cancer from other neoplasms as they all present with non specific constitutional symptoms. Hence, differentiation is primarily based on anatomic location:[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]
