For many years, the diagnosis and classification of gliomas have been based on histology. Although studies including large populations of patients demonstrated the prognostic value of histologic phenotype, variability in outcomes within histologic groups limited the utility of this system. Nonetheless, histology was the only proven and widely accessible tool available at the time, thus it was u...
Primary cancers of the appendix are rare and are frequently diagnosed after surgery for appendicitis, presumed ovarian primary malignancy, or other indications. Primary appendix cancers are histologically diverse, and classification of these tumors has historically been confusing because of the nonstandardized nomenclature that is used. This review aimed to describe the epidemiology, presentati...
BACKGROUND Histologic characteristics have proven to be very useful for classifying different types of tumors of the pancreas. As a result, the major tumor types in the pancreas have long been classified based on their microscopic appearance. MAIN BODY Recent advances in whole exome sequencing, gene expression profiling, and knowledge of tumorigenic pathways have deepened our understanding of...
Flow cytometric analyses of cellular DNA, RNA, and double-stranded RNA content were performed on lymph nodes and extranodal tissue from 177 patients with non-Hodgkin's lymphoma. With increasing histologic grade, a higher incidence of aneuploidy, higher proliferative activity, and higher total and double-stranded RNA content were found. Despite considerable cytometric heterogeneity within histol...
OBJECTIVES Triple-negative breast cancer is regarded as an aggressive disease that affects a young patient population and for which effective targeted therapy is not yet available. METHODS Intense efforts have been made to gain a better understanding of this heterogeneous group of tumors from the histologic to the genomic and molecular levels. RESULTS Progress has been made, including the a...
Thymic epithelial tumor is a distinctive pathologic entity exhibiting variable histologic features and heterogeneous oncologic behavior. Among the various classification systems, that of the World Health Organization has been adopted because of good correlation between histologic appearance and oncologic behavior. Radiologically, a smooth contour and round shape are most suggestive of a type-A ...
IgA nephropathy is glomerular disease first described in 1968 by Berger, named after him Morbus Berger. The disease is characterized by the presence of IgA dominant or codominant immunoglobulin deposits in glomerular mesangium which can be demonstrated by immunofluorescence.
