Despite major improvements concerning its diagnosis and treatment, pancreatic ductal adenocarcinoma (PDAC) remains an aggressive disease with an extremely poor prognosis. Adenocarcinoma not otherwise specified, also adenocarcinoma NOS, is a non-specific malignant diagnosis that without further information is not very useful for treatment decisions. & Klimstra, D. S. (2003). Pancreatic epithelial neoplasms can be simply classified into solid and cystic neoplasms based on their gross appearances, as illustrated in Figure 1.Pancreatic ductal adenocarcinoma (DADC) and its variants, such as colloid carcinoma and medullary carcinoma, account for approximately 85% of neoplasms, followed by intraductal papillary mucinous neoplasms (IPMNs) at 3% to 5%, and pancreatic . Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer, comprising 90% of all malignant pancreatic neoplasms, with a dismal 5-year survival rate of 8%.1, 2 In the United States, it is the fourth leading cause of cancer death in both males and females.

The image shows mucin rich matrix created by dissecting pools of mucin which destroy the native lung architecture. In the last twenty years several advances have been registered in the field of pancreatic pathology that permit a better understanding of the biological mechanisms involved in pancreatic cancer (PC) and a better treatment of the patients. Acinar cell carcinoma: 1 - 2 % of cases in the head of pancreas and uniform cells with cytoplasmic granules resembling normal pancreas.

For prognostic reasons, the term mucinous carcinoma should be applied to pure tumors showing stromal mucin in >90 of the tumor. It is noteworthy that colloid (mucinous) carcinoma of the breast and pancreas are characterized by similar findings, that is, a band-like staining on the surface of the cell clusters for apical . The image shows mucin rich matrix created by dissecting pools of mucin which destroy the native lung architecture. Colloid (mucinous) carcinomas of the pancreas are frequently associated with high-grade intestinal-type intraductal papillary neoplasms of the pancreas and are characterized by the presence of extracellular mucin aggregates ( Figure 2E,F ). Clinical findings Produces a cystic mass (Table 3-1), most commonly located in head of pancreas (Figure 3-1). It only briefly discusses metastatic lesions.

Pathologic classification of "pancreatic cancers": current concepts and challenges As the most common and most important cancer of the pancreas, with rapid mortality and now also as the third leading cause of cancer-related deaths in the United States, pancreatic ductal adenocarcinoma (PDAC) has become synonymous with "pancreas cancer". Pancreatic carcinogenesis results from a stepwise progression in which accumulating genetic alterations drive neoplastic progression in well-defined precursor lesions, ultimately giving rise to an invasive adenocarcinoma. Lymph node and liver metastases can be present in 50 % of cases at diagnosis with aggressive behaviour. The commonly used terms "carcinoma of the pancreas" or "pancreatic cancer" usually refer to ductal adenocarcinoma (including its subtypes), which represents 85 to 90 percent of all pancreatic neoplasms. 165 pancreatobiliary neoplasms (34 intraductal papillary mucinous neoplasms [IPMNs], 19 pancreatic ADCAs, 112 cholangiocarcinomas [CCs]), and 35 gastric, 13 small bowel, 36 ampullary (AMP), and 46 CRC ADCAs.

Pure mucinous carcinomas comprise up to 2% of all breast cancers. Infiltrating duct carcinoma. Colloid nodules are composed of irregularly enlarged follicles containing abundant colloid. The tumors are well-circumscribed and have a gelatinous, bluish-gray cut surface. Pathogenesis of colloid (pure mucinous) carcinoma of exocrine organs: coupling of gel-forming mucin (MUC2) production with altered cell polarity and abnormal cell-stroma interaction may be the key factor in the morphogenesis and indolent behavior of colloid carcinoma in the breast and pancreas. Pancreatic intraepithelial neoplasia, grade 3 (PanIN-3) 8148/2 Intraductal papillary mucinous neoplasm with low- or intermediate- 8453/0 . It's also possible for adenocarcinoma to develop from the cells that create pancreatic enzymes. intraluminal most are not mucinous high grade/ low grade may be secondary cystic change.

It is more common in men, with peak age around 65 years. 31 Undifferentiated carcinoma with osteoclast-like giant cells is composed of single . In regard to the clinical pathology, mucinous colorectal adenocarcinoma is found more frequently in the proximal colon than in the rectal or distal colon [ 4, 9, 10 ]. but this may not be evident in small biopsy . Colloid carcinoma (CC) of the pancreas, also known as muci- also known as muci- nous non-cystic car cinoma, is a rare subtype of pancreatic cancer that only accounts for only 1- 3% of the malignant. Mucinous colorectal adenocarcinoma is a distinct subtype of colorectal cancer (CRC) characterized by the presence of abundant extracellular mucin which accounts for at least 50% of the tumor volume.
