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. Types * Pancreatic intraductal papillary mucinous tumors (most common diagnosis - 52.6%) * Pancreatic serous cystic tumors (20.6%) ** Pancreatic serous cystadenoma ** Pancreatic serous cystadenocarcinoma * Pancreatic mucinous cystic tumors (13.4%) ** Pancreatic mucinous cystadenoma Pancreatic mucinous cystadenoma, also known as "mucinous cystadenoma of the pancreas", is a benign tumour of pancreas. It is one of the cystic lesions of the pancreas. Pathology Microscopy File:Mucinous cystadenoma of the pancreas 5.jpg, Mu ... ** Pancreatic mucin ...

Solid Pseudopapillary Tumor
A solid pseudopapillary tumour is a low-grade malignant neoplasm of the pancreas of :wikt:papilla, papillary architecture that typically afflicts young women. Signs and symptoms Solid pseudopapillary tumours are often asymptomatic and are identified incidentally on imaging performed for unrelated reasons. Less often, they may cause abdominal pain. Solid pseudopapillary tumours tend to occur in women, and most often present in the third decade of life. Anatomy Gross morphology Solid pseudopapillary tumours are typically round, well-demarcated, measuring 2–17 cm in diameter (average 8 cm), with solid and cystic areas with hemorrhage on cut sections. Histomorphology Solid pseudopapillary tumours consist of solid sheets of cells that are focally dyscohesive. The cells in the lesion usually have uniform nucleus (cell), nuclei with occasional nuclear grooves, eosinophilic or clear cytoplasm and Periodic acid-Schiff stain, PAS positive eosinophilic intracytoplasmic globule ...

Pancreatic Intraductal Papillary Mucinous Tumor
The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e. it has both an endocrine and a digestive exocrine function. 99% of the pancreas is exocrine and 1% is endocrine. As an endocrine gland, it functions mostly to regulate blood sugar levels, secreting the hormones insulin, glucagon, somatostatin, and pancreatic polypeptide. As a part of the digestive system, it functions as an exocrine gland secreting pancreatic juice into the duodenum through the pancreatic duct. This juice contains bicarbonate, which neutralizes acid entering the duodenum from the stomach; and digestive enzymes, which break down carbohydrates, proteins, and fats in food entering the duodenum from the stomach. Inflammation of the pancreas is known as pancreatitis, with common causes including chronic alcohol use and gallstones. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pancreatic Serous Cystadenocarcinoma
The pancreas is an organ of the digestive system and endocrine system of vertebrates. In humans, it is located in the abdominal cavity, abdomen behind the stomach and functions as a gland. The pancreas is a mixed or heterocrine gland, i.e. it has both an endocrine and a digestive exocrine function. 99% of the pancreas is exocrine and 1% is endocrine. As an endocrine gland, it functions mostly to regulate blood sugar levels, secreting the hormones insulin, glucagon, somatostatin, and pancreatic polypeptide. As a part of the digestive system, it functions as an exocrine gland secreting pancreatic juice into the duodenum through the pancreatic duct. This juice contains bicarbonate, which neutralizes acid entering the duodenum from the stomach; and digestive enzymes, which break down carbohydrates, proteins, and lipids, fats in food entering the duodenum from the stomach.
