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]
[citation needed] Indications for surgical resection include obstructive jaundice, an enhancing mural nodule >5 mm, and pancreatic duct dilation (>10 mm). [ 12 ] Surgery can include the removal of the head of the pancreas (a pancreaticoduodenectomy ), removal of the body and tail of the pancreas (a distal pancreatectomy ), or rarely removal of ...
Jaundice can be a symptom, due to biliary obstruction from a pancreatic tumor. Since pancreatic cancer usually does not cause recognizable symptoms in its early stages, the disease is typically not diagnosed until it has spread beyond the pancreas itself. [4] This is one of the main reasons for the generally poor survival rates.
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.
[3] [4] [5] This abnormal growth usually forms a mass, which may be called a tumour or tumor. [6] ICD-10 classifies neoplasms into four main groups: benign neoplasms, in situ neoplasms, malignant neoplasms, and neoplasms of uncertain or unknown behavior. [7] Malignant neoplasms are also simply known as cancers and are the focus of oncology.
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 ...

Acinar cell carcinoma of the pancreas, also acinar cell carcinoma, is a rare malignant exocrine tumour of the pancreas. It represents 5% of all exocrine tumours of the pancreas, making it the second most common type of pancreatic cancer. [1] It is abbreviated ACC. It typically has a guarded prognosis.
