Newer diagnostic modalities have revolutionized the pathologist’s approach to diagnosing thyroid malignancies. Molecular characterization of these malignancies has helped circumvent common morphologic diagnostic difficulties by integrating their genotypic, phenotypic, and immunohistochemical features.
BRAF
V600E mutation has been characterized as highly specific for thyroid carcinoma, especially papillary thyroid carcinoma (PTC); human bone marrow endothelial marker-1 (HBME-1) and galectin-3 are also such markers that are highly specific for PTC. We propose to study HBME-1 and galectin-3 expression and
BRAF
V600E mutation in thyroid neoplasms and do a comparative analysis to determine whether there is a correlation between
BRAF
V600E expression and that of HBME-1 and galectin-3. We further propose to analyze the individual and combined diagnosed utility of the above-mentioned ancillary diagnostic techniques.
Osteoclast-like giant cell tumor of the pancreas is a rare non-endocrine neoplasm composed of reactive multinucleated giant cells admixed with mononuclear stromal cells. We report a case of osteoclast-like giant cell tumor of the pancreas in a 58-year-old female with vague clinical symptoms. Endoscopic ultrasound-guided aspirate from the mass revealed numerous characteristic osteoclast-like giant cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
