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] |
Micrograph
A micrograph or photomicrograph is a photograph or digital image taken through a microscope or similar device to show a magnified image of an object. This is opposed to a macrograph or photomacrograph, an image which is also taken on a microscope but is only slightly magnified, usually less than 10 times. Micrography is the practice or art of using microscopes to make photographs. A micrograph contains extensive details of microstructure. A wealth of information can be obtained from a simple micrograph like behavior of the material under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental analysis and so on. Micrographs are widely used in all fields of microscopy. Types Photomicrograph A light micrograph or photomicrograph is a micrograph prepared using an optical microscope, a process referred to as ''photomicroscopy''. At a basic level, photomicroscopy may be performed simply by connecting a camera to a microscope, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgery
Surgery ''cheirourgikē'' (composed of χείρ, "hand", and ἔργον, "work"), via la, chirurgiae, meaning "hand work". is a medical specialty that uses operative manual and instrumental techniques on a person to investigate or treat a pathological condition such as a disease or injury, to help improve bodily function, appearance, or to repair unwanted ruptured areas. The act of performing surgery may be called a surgical procedure, operation, or simply "surgery". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments or surgical nurse. The person or subject on which the surgery is performed can be a person or an animal. A surgeon is a person who practices surgery and a surgeon's assistant is a person who practices surgical assistance. A surgical team is made up of the surgeon, the surgeon's assistant, an anaesthetist, a circulating nurse and a surgical technologist. Surgery usually spa ...

Solid Pseudopapillary Neoplasm
A solid pseudopapillary tumour is a low-grade malignant neoplasm of the pancreas of 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 nuclei with occasional nuclear grooves, eosinophilic or clear cytoplasm and PAS positive eosinophilic intracytoplasmic globules. Necrosis is usually present and, as cell death prefere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ovarian Serous Cystadenoma
Ovarian serous cystadenoma, also (less precisely) known as serous cystadenoma, is the most common ovarian neoplasm, representing 20% of ovarian neoplasms, and is benign. It has a very superficial resemblance to the most common type of ovarian cancer (serous carcinoma of the ovary) under the microscope; however, (1) it is virtually impossible to mix-up with its malignant counterpart (serous carcinoma), and (2) does not share genetic traits of indeterminate serous tumours, also called ''serous borderline tumours'', that may transform into serous carcinoma. Serous cystadenomas (of the ovary) are not related to serous cystadenomas of the pancreas, i.e. the presence of an ovarian ''or'' pancreatic one does ''not'' suggest an increased risk for the other one. Diagnostic Procedures includes initially ultrasound or colour doppler study to know about size and nature of mass and sometimes CECT. Blood investigation includes CA-125 level for screening and further CEA, beta hCG levels, AFP, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Laparoscopy
Laparoscopy () is an operation performed in the abdomen or pelvis using small incisions (usually 0.5–1.5 cm) with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.MedlinePlus > Laparoscopy Update Date: 21 August 2009. Updated by: James Lee, MD // No longer valid Laparoscopic surgery, also called minimally invasive procedure, bandaid surgery, or keyhole surgery, is a modern surgical technique. There are a number of advantages to the patient with laparoscopic surgery versus an exploratory laparotomy. These include reduced pain due to smaller incisions, reduced hemorrhaging, and shorter recovery time. The key element is the use of a laparoscope, a long fiber optic cable system that allows viewing of the affected area by snaking the cable from a more distant, but more easily accessible location. Laparoscopic surgery includes operations within the abdominal or pelvic cavities, whereas keyhole surgery perform ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distal Pancreatectomy
In medicine, a pancreatectomy is the surgical removal of all or part of the pancreas. Several types of pancreatectomy exist, including pancreaticoduodenectomy (Whipple procedure), distal pancreatectomy, segmental pancreatectomy, and total pancreatectomy. In recent years, the TP-IAT (Total Pancreatectomy with Islet Autotransplantation) has also gained respectable traction within the medical community. These procedures are used in the management of several conditions involving the pancreas, such as benign pancreatic tumors, pancreatic cancer, and pancreatitis. Indications It is performed for a variety of reasons, including: * Inflammation ** Necrotising pancreatitis ** Chronic pancreatitis with pain * Trauma * Neoplasms ** Adenocarcinoma (85%) ** Cystadenoma (mucinous/serous) ** Cystadenocarcinoma ** Islet cell tumors (neuroendocrine tumors) ** Papillary cystic neoplasms ** Lymphoma ** Acinar cell tumors * Severe hyperinsulinemic hypoglycemia Types The most common surgical proc ...

Pancreaticoduodenectomy
A pancreaticoduodenectomy, also known as a Whipple procedure, is a major surgical operation most often performed to remove cancerous tumours from the head of the pancreas. It is also used for the treatment of pancreatic or duodenal trauma, or chronic pancreatitis. Due to the shared blood supply of organs in the proximal gastrointestinal system, surgical removal of the head of the pancreas also necessitates removal of the duodenum, proximal jejunum, gallbladder, and, occasionally, part of the stomach. Anatomy involved in the procedure The most common technique of a pancreaticoduodenectomy consists of the en bloc removal of the distal segment (antrum) of the stomach, the first and second portions of the duodenum, the head of the pancreas, the common bile duct, and the gallbladder. Lymph nodes in the area are often removed during the operation as well (lymphadenectomy). However, not all lymph nodes are removed in the most common type of pancreaticoduodenectomy because studies sho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johns Hopkins University
Johns Hopkins University (Johns Hopkins, Hopkins, or JHU) is a private university, private research university in Baltimore, Maryland.

H&E Stain
Hematoxylin and eosin stain ( or haematoxylin and eosin stain or hematoxylin-eosin stain; often abbreviated as H&E stain or HE stain) is one of the principal tissue stains used in histology. It is the most widely used stain in medical diagnosis and is often the gold standard. For example, when a pathologist looks at a biopsy of a suspected cancer, the histological section is likely to be stained with H&E. H&E is the combination of two histological stains: hematoxylin and eosin. The hematoxylin stains cell nuclei a purplish blue, and eosin stains the extracellular matrix and cytoplasm pink, with other structures taking on different shades, hues, and combinations of these colors. Hence a pathologist can easily differentiate between the nuclear and cytoplasmic parts of a cell, and additionally, the overall patterns of coloration from the stain show the general layout and distribution of cells and provides a general overview of a tissue sample's structure. Thus, pattern recogniti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pathologist
Pathology is the study of the causal, causes and effects of disease or injury. The word ''pathology'' also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices. However, when used in the context of modern medical treatment, the term is often used in a narrower fashion to refer to processes and tests that fall within the contemporary medical field of "general pathology", an area which includes a number of distinct but inter-related medical specialties that diagnose disease, mostly through analysis of tissue (biology), tissue, human cell, cell, and body fluid samples. Idiomatically, "a pathology" may also refer to the predicted or actual progression of particular diseases (as in the statement "the many different forms of cancer have diverse pathologies", in which case a more proper choice of word would be "Pathophysiology, pathophysiologies"), and the affix ''pathy'' is sometimes used to indicate a state of disease ...
