surgical resection. 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 tumor. Anatomy of the pancreas. Specialty. Gastroenterology, Hepatology, Oncology. Usual onset. Adults [1] 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.
Globally, pancreatic cancer is the 11th most-common cancer in women and the 12th most-common in men. [10] The majority of recorded cases occur in developed countries . [ 10 ] People from the United States have an average lifetime risk of about 1 in 67 (or 1.5%) of developing the disease, [ 114 ] slightly higher than the figure for the UK. [ 115 ]
In contrast, pseudopapillae (such as in solid pseudopapillary tumours) are nests of proliferating cells that eventually grow to become almost back-to-back, with cells in the centers of nests disintegrating, leaving rims of cells lining the periphery of each nest. Discohesive cells and some formations lacking central blood vessels are visual clues.
Pancreatic neuroendocrine tumours ( PanNETs, PETs, or PNETs ), often referred to as "islet cell tumours", [ 1][ 2] or "pancreatic endocrine tumours" [ 3][ 4] are neuroendocrine neoplasms that arise from cells of the endocrine ( hormonal) and nervous system within the pancreas . PanNETs are a type of neuroendocrine tumor, representing about one ...
However, the majority of patients with pancreatic cancer present with metastatic or locally advanced un-resectable disease; [9] thus only 15–20% of patients are candidates for the Whipple procedure. Surgery may follow neoadjuvant chemotherapy, which aims to shrink the tumor and increase the likelihood of complete resection. [10]

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.
