Serous neoplasms are uncommon, usually cystic tumors that account for less than 1% of all primary pancreatic lesions. They consist predominantly of a monomorphic epithelial cell population with a glycogen-rich, clear cytoplasm, reminiscent of clear cell renal cell carcinoma, with which serous neoplasms share an association with underlying VHL loss-of-function mutations. Serous neoplasms have no metastatic potential. Accurate recognition of this entity, including its various architectural subtypes, is critical to appropriate prognostication and treatment. Immunohistochemical detection of inhibin and calponin expression, along with the absence of both estrogen and progesterone receptors and nuclear β-catenin, can help to distinguish serous neoplasms from mimics. With the advent of minimally invasive and molecularly driven diagnostic techniques, the pathologist's role in the assessment and management of serous neoplasms has become increasingly complex and important. We provide an update on the histologic, immunohistochemical, and molecular features of pancreatic serous neoplasms for the practicing pathologist.

Microcystic variant of serous cystadenoma of the pancreas is a rare neoplasm; essentially located in the body or tail of the pancreas and associated with the von Hippel-Lindau. Often, patients are asy...
Prognostic factors for solid pseudopapillary neoplasms (SPN) of the pancreas have been incompletely defined in the literature. We aimed to use the National Cancer Database to describe survival and cha...
The aim of this study was to evaluate the clinicopathological features of solid pseudopapillary neoplasms (SPNs).
Little is known about chromogranin A (CgA) during follow-up of gastroenteropancreatic neuroendocrine neoplasms. We hypothesized that serial CgA monitoring might be useful for the assessment of tumor p...
Mutations at hot spots in GNAS, which encodes stimulatory G-protein, alpha subunits, are detected in ∼60% of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas. We generated mice with ...
Pancreatic cysts are common, and some pancreas cysts have malignant potential. Usual treatment of these cysts is either observation or surgical removal of part or all of the pancreas. Mini...
Chart review evaluating outcome of patients in whom following resection of a tumor involving the head of the pancreas no anastomosis of the pancreatic stump was done to the gastrointestina...
The overlap of morphological imaging features results in many incidentally detected pancreatic cystic neoplasms going undiagnosed, including benign serous cystic neoplasms (SCN) and potent...
The goal of this clinical research study is to learn if fulvestrant and palbociclib can help to control low-grade serous ovarian cancer. The safety of this drug combination will also be st...
The pupose of this study is to evaluate the safety and efficacy of irreversible electroporation (IRE) for refractory neoplasms in liver and pancreas, the investigators used preoperative an...
Neoplasms of the thin serous membrane that envelopes the lungs and lines the thoracic cavity. Pleural neoplasms are exceedingly rare and are usually not diagnosed until they are advanced because in the early stages they produce no symptoms.
Neoplasms containing cyst-like formations or producing mucin or serum.
Neoplasms composed of tissue of the mesothelium, the layer of flat cells, derived from the mesoderm, which lines the body cavity of the embryo. In the adult it forms the simple squamous epithelium which covers all true serous membranes (peritoneum, pericardium, pleura). The concept does not refer to neoplasms located in these organs.

Review of the medical necessity of hospital or other health facility admissions, upon or within a short time following an admission, and periodic review of services provided during the course of treatment.
Formal programs for assessing drug prescription against some standard. Drug utilization review may consider clinical appropriateness, cost effectiveness, and, in some cases, outcomes. Review is usually retrospective, but some analysis may be done before drugs are dispensed (as in computer systems which advise physicians when prescriptions are entered). Drug utilization review is mandated for Medicaid programs beginning in 1993.
Hepatology is the study of liver, gallbladder, biliary tree, and pancreas, and diseases associated with them. This includes viral hepatitis, alcohol damage, cirrhosis and cancer. As modern lifestyles change, with alcoholism and cancer becoming more promi...
Pancreatitis Acute pancreatitis is inflammation of the pancreas caused by the release of activated pancreatic enzymes. Common triggers are biliary tract disease and chronic heavy alcohol intake. Diagnosis is based on clinical presentation...
