Clinical Radiology is published by Elsevier on behalf of The Royal College of Radiologists.Clinical Radiology is an International Journal bringing you original research, editorials and review articles on all aspects of diagnostic imaging, including: Computed tomography Magnetic resonance imaging Ultrasonography Digital radiology p53 expression can also aid in the classification of dysplasia as up to 60% of cases of high-grade dysplasia and carcinoma express p53 in comparison to just 30% of cases classified as indefinite for dysplasia and low grade dysplasia (24,25). The ovary is made up of three different cell types including epithelial cells, germ cells, and stromal cells. Ovarian mucinous This is usually an incidental finding noted in an asymptomatic individual, however spontaneous splenic rupture has been reported[36]. Although rare, angiosarcoma is the most common primary non-hematopoietic malignant tumor of the spleen[7]. Incidence and mortality from stomach cancer in Japan, Slovenia and the USA. Splenic angiosarcoma. Differential considerations include cystadenoma and cystadenocarcinoma. Splenic lymphangioma. Mucinous cystic neoplasms occur almost exclusively in perimenopausal women in the body or tail of pancreas. Ultrasound uses sound waves, and CT uses X-rays, to look at tissues inside the body. The presence of occasional squamoid nests is characteristic for this lesion (178). Immunohistologic analysis of gastrointestinal and pulmonary carcinoid tumors.

Vulvar Pagets disease with underlying adenocarcinoma simulating breast carcinoma: case report and review of the literature. Omental cake refers to infiltration of the omental fat by material of soft-tissue density. Splenic angiosarcoma appears as an aggressive splenic mass or masses with associated splenomegaly[8]. Ductal differentiation is defined as ductular formation and mucin production (174) and presence of ductal markers like CEA, CK19 and CA19.9, while ductal acinar cells can be highlighted by pancreatic enzymes like trypsin, chymotrypsin and lipase (186,187). A. Gastric adenocarcinoma- diffuse type/signet ring cell carcinoma; B. On MRI, the mass is isointense on the T1-weighted inphase (C) and is slightly hyperintense on the T2-weighted fat-saturated sequence (asterisk) (D). These tumors are often large and can occur anywhere within the pancreas but are more often found at the head of the pancreas. The majority of the mass lesions within the liver are benign lesions such as focal nodular hyperplasia (FNH), regenerative nodules, adenoma, cirrhosis, and vascular lesions. Expression of the intestinal transcription factor CDX2 in carcinoid tumors is a marker of midgut origin. Multiple lesions of the spleen: differential diagnosis of cystic and solid lesions. Cytokeratin 7 and 20 expression in cholangiocarcinomas varies along the biliary tract but still differs from that in colorectal carcinoma metastasis. Esophageal cancer Symptoms often include difficulty in swallowing and weight loss. Features associated with a more aggressive behavior include a high mitotic rate (>5/per 50 hpf), large size (>5 cm), invasion, location within the fundus or gastrointestinal junction, coagulative necrosis, ulceration and epithelioid morphology (55,56). Immunohistochemical expression of chromogranins A and B, prohormone convertases 2 and 3, and amidating enzyme in carcinoid tumors and pancreatic endocrine tumors. sharing sensitive information, make sure youre on a federal Presentation schedule is subject to change. Therefore, the radiology report should detail the spread of the disease, describing the primary tumor whenever possible and detailing the organs involved. Lung adenocarcinoma is further classified into several MRI. Portela-Gomes GM, Hacker GW, Weitgasser R. Neuroendocrine cell markers for pancreatic islets and tumors. Both of these benign bile duct proliferations have an immunohistochemical profile similar to that of pancreatic ductal adenocarcinoma and are positive for CK7, CK17, MUC1 and MUC5AC (213). Stromal tumors comprise the majority of primary nonepithelial neoplasms in the stomach, and GIST is the most common GI mesenchymal neoplasm. (B) Contrast-enhanced CT shows a lobulated hypodense mass in the spleen (*). Immunohistochemical stains may assist in the assessment of dysplasia as p53 expression and Ki-67 positive dysplastic cells also increase as dysplasia increases (36). Thompson WM, Levy AD, Aguilera NS, Gorospe L, Abbott RM. Most cases are sporadic but reported risk factors include sporadic adenomatous polyps, familial adenomatous polyposis and Crohns disease. Histologically, the tumor has a lobular appearance with well-defined islands of small epithelial cells separated by fibrous bands with a geographic pattern of lighter and darker staining cells due to the different cell types present. HCC is the third leading cause of cancer-related deaths worldwide. Two major histologic types have been described: an intestinal type, arising from the overlying intestinal mucosa of the papilla (intestinal type adenocarcinoma of duodenal papillary origin) and a pancreatobiliary type, derived from the ductal epithelium which penetrates the duodenal muscularis propria (ampullary carcinoma of pancreatobiliary origin) (69). Despite the presence of squamoid nests, pancreatoblastomas are negative for squamous markers (negative for high molecular weight keratins CK14, CK5/6, and CK17) and CK7 (179) but positive for CK8, CK18, CK19, EMA and cytoplasm and membranous -catenin (180).

The two main types of GIM are the complete type (type I) characterized by its resemblance to normal small intestinal mucosa with absorptive cells, Paneth cells and goblet cells; and the incomplete type (types II and III) where there are columnar and goblet cells. IM without dysplasia is usually positive for HepPar-1 and MUC2 and negative for AMCAR, whereas IM with dysplasia and adenocarcinoma often express AMCAR but not HepPar-1 or MUC2 (28,29). Nowak MA, Guerriere-Kovach P, Pathan A, et al. Adenocarcinoma of the lung Bhatia K, Sahdev A, Reznek RH. These tumors cause obstruction of the bile duct even at a very small size and hence patients often present early in the disease course with jaundice. Other patterns of enhancement that can be seen are immediate homogeneous enhancement with persistent delayed enhancement and peripheral enhancement with persistent lack of central enhancement on delayed images. A survey of 742 cases and further characterization of rare CD43. Pancreatic neuroendocrine tumors (PNETs) are rare neoplasms with an incidence of 1 per 100,000 individuals per year and comprising just 1-2% of all pancreatic tumors (170).
