Pancreatic mucinous cystic neoplasm (MCN) is a type of cystic lesion that occurs in the pancreas. Amongst individuals undergoing surgical resection of a pancreatic cyst, about 23 percent were mucinous cystic neoplasms. These lesions are benign, though there is a high rate of progression to cancer. As such, surgery should be pursued when feasible.
Cystic lesions of the pancreas are a group of pancreatic lesions characterized by a cystic appearance. They can be benign or malignant. [citation needed] Cystic lesions are found in 20.6% of all pancreatectomy specimens. Among this heterogeneous group, benign neoplasms predominate, particularly those with mucinous lining.
A pancreatic cyst is a fluid filled sac within the pancreas. The prevalence of pancreatic cysts is 2-15% based on imaging studies, but the prevalence may be as high as 50% based on autopsy series. [1] Most pancreatic cysts are benign and the risk of malignancy (pancreatic cancer) is 0.5-1.5%.
Gross pathology: Main duct, branch duct, and mixed duct lesions, which determines surgical management. Main duct lesion is the segmental or diffuse dilatation of main pancreatic duct greater than 5 mm without other causes of obstruction. Meanwhile, branch duct lesion is the pancreatic cyst more than 5 mm that communicates with the main duct.
It is usually solitary and found in the body or tail of the pancreas, and may be associated with von Hippel–Lindau syndrome. [2] In contrast to some of the other cyst-forming tumors of the pancreas (such as the intraductal papillary mucinous neoplasm and the pancreatic mucinous cystadenoma), serous cystic neoplasms are almost always entirely ...
A pancreatic tumor is an abnormal growth in the pancreas. [1] In adults, almost 90% are pancreatic cancer and a few are benign. [1] Pancreatic tumors are rare in children. [1] Classification is based on cellular differentiation (ductal, acinar, neuroendocrine, other) and gross appearance (intraductal, cystic, solid). [1]
A pancreatic pseudocyst is a circumscribed collection of fluid rich in pancreatic enzymes, blood, and non-necrotic tissue, typically located in the lesser sac of the abdomen. Pancreatic pseudocysts are usually complications of pancreatitis , [ 5 ] although in children they frequently occur following abdominal trauma .
Pancreatic neuroendocrine tumors may arise in the context of multiple endocrine neoplasia type 1, Von Hippel–Lindau disease, neurofibromatosis type 1 (NF-1) or tuberose sclerosis (TSC) [31] [32] Analysis of somatic DNA mutations in well-differentiated pancreatic neuroendocrine tumors identified four important findings: [33] [7]
