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%.
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 benign. There are some exceptions; rare case reports have described isolated malignant serous cystadenocarcinomas. [3]
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.
These types of tumors are common and mostly benign, although certain subtypes have varying malignant potential. [6] The second broad category of pancreatic tumor types are neuroendocrine tumors (also known as "endocrine" or "islet cell tumors").
Pancreatic mucinous cystic neoplasms are a broad group of pancreas tumors that have varying malignant potential. They are being detected at a greatly increased rate as CT scans become more powerful and common, and discussion continues as how best to assess and treat them, given that many are benign.
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.
Intraductal papillary mucinous neoplasm (IPMN) is a type of tumor that can occur within the cells of the pancreatic duct. IPMN tumors produce mucus, [1] and this mucus can form pancreatic cysts. [2] Although intraductal papillary mucinous neoplasms are benign tumors, they can progress to pancreatic cancer. [1]
Pancreatic mucinous cystadenoma or mucinous cystadenoma of the pancreas (MCN) are a type of mucinous cystic neoplasm of the pancreas. [3] The cure rate is very high in cases on benign cystic lesions, but the case changes if malignant changes ensue. [4] Benign cystadenomas are the most common cystic tumors of the pancreas accounting for 75% of ...
