BACKGROUND Gastrinomas are located more frequently in the pancreas, which normally has no cells that can produce gastrin. They have a more aggressive course than other pancreatic endocrine tumors and extrapancreatic gastrinomas associated with multiple endocrine neoplasia Type 1 syndrome. The current study analyzed immunophenotypes of gastrinomas and(More)
Primary liver tumors, including 7 low-grade hepatocellular carcinomas (HC), 12 average-grade HC (including 2 mixed tumors and 2 cholangiocellular carcinomas (ChC)), obtained from 23 patients, were histologically, immunohistochemically, and electron microscopically. Certain markers were immunohistochemically studied to identify HC and ChC and differentiate(More)
Mucins and glycoprotein CD10 expression in 55 carcinomas of the stomach has been studied by immunohistochemistry. According to a profile of mucins and CD10 expression, 3 immunophenotypic variants of carcinoma were founded: gastric, intestinal and gastro-intestinal. Gastric and gastro-intestinal variants were more frequently than intestinal one. The(More)
OBJECTIVE To analyze 60 cases of solid pseudopapillary tumors (SPTs) of the pancreas, to reveal their most characteristic clinical and morphological features, and to study their possible histogenesis. MATERIAL AND METHODS Sixty cases of SPTs of the pancreas underwent clinical, morphological, and immunohistochemical (IHC) examinations; a comparison group(More)
The article is about the characteristics of the morphofunctional state of the upper gastrointestinal tract (UGIT) in children with obesity. Under supervision there were 130 children aged 10-16 years: study group--80 children with obesity (42 boys and 38 girls) (SDS BMI 2.0), the comparison group--50 children with normal body weight (32 boys and 18 girls)(More)
Gliomas are the most common tumors of the central nervous system (CNS). Malignant astrocytic gliomas account for 50% of all primary brain tumors. Cells of origin are unknown for the majority of brain tumors: CNS tumors have frequently in their content many histological forms and their classification will depend on what the parts of neoplasm that will be(More)
