Tumour Of Pancreas
Pancreatic tumors (Pancreatic cancer) are often broken down into exocrine or endocrine tumors. Each different type of pancreatic tumor has a different appearance when examined under a microscope. These unique microscopic features and genetic markers are what allow for proper diagnosis and treatments in patients with pancreatic cancers. Types When talking about pancreatic cancers, the most common type is pancreatic adenocarcinoma, which accounts for greater than 85% of all pancreas cancers. Adenocarcinomas are exocrine tumors of the pancreas, which implies that they begin within the part of the pancreas responsible for creating digestive enzymes. Different subtypes of exocrine adenocarcinomas exist, with the most common being pancreatic ductal adenocarcinoma (PDAC). Following PDACs, acinar cell carcinomas account for 5% of exocrine pancreatic cancers and can be "functioning", and overproduce certain molecules that can lead to some of the signs and symptoms that are often encountere ...

Cystic Lesions Of The Pancreas
Cystic lesions of the pancreas are a group of pancreatic lesions characterized by a cystic appearance. They can be benign or malignant. Cystic lesions are found in 20.6% of all pancreatectomy specimens. Among this heterogeneous group, benign neoplasms predominate, particularly those with mucinous lining. Age at presentation, gender, location and tumor size are highly variable, with the exception of solid pseudopapillary tumor.

Mucinous Cystadenoma
Mucinous cystadenoma is a benign cystic tumor lined by a mucinous epithelium. It is a type of cystic adenoma (cystadenoma). Mucinous cystadenomata may arise in a number of locations; however, mucinous cystadenoma at different locations are not generally considered to be related to one another. Overview Mucinous cystadenomas may be found in the: *Ovary— ovarian mucinous cystadenoma *Pancreas—pancreatic mucinous cystadenoma *Peritoneum— peritoneal mucinous cystadenoma *Liver— mucinous cystadenoma of the liver *Vermiform appendix— appendiceal mucinous cystadenoma (see cystadenoma) Ovarian mucinous cystadenoma Mucinous cystadenomas make up 15–20% of all ovarian tumors. They often become very large and can extend up into the abdomen. These tumors are usually evaluated using ultrasound, CT scan, or MRI. Findings on imaging studies are nonspecific. These ovarian tumors are usually multi-septated, cystic masses with thin walls. They also contain varying amounts of solid ti ...

Pancreatic Cyst
A pancreatic cyst is a fluid filled sac within the pancreas. Causes range from benign to malignant. Pancreatic cysts can occur in the setting of pancreatitis, though they are only reliably diagnosed 6 weeks after the episode of acute pancreatitis. Benign tumors such as serous cystadenomas can occur. Main branch intraductal papillary mucinous neoplasms (IPMNs) are associated with dilatation of the main pancreatic duct, while side branch IPMNs are typically benign, and not associated with dilatation. MRCP can help distinguish the position of the cysts relative to the pancreatic duct, and direct appropriate treatment and follow-up. The most common malignancy that can present as a pancreatic cyst is a mucinous cystic neoplasm. Follow up guidelines Cysts from 1–5 mm on CT or ultrasound Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" (audible) sound in its physical ...

Pancreatic Serous Cystadenoma
Pancreatic serous cystadenoma is a benign tumour of the pancreas. It is usually found in the tail of the pancreas, and may be associated with von Hippel–Lindau syndrome. 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. In addition, serous cystic neoplasms slowly grow, and if they grow large enough they can press on adjacent organs and cause symptoms. Signs and symptoms In most cases, serous cystadenomas of the pancreas are asymptomatic. However, large cysts may cause symptoms related to their size. Classification Pathologists classify serous cystic neoplasms into two broad groups. Those that are benign, that have not spread to other organs, are designated "serous cystadenoma". Serous cystadenomas can ...
