General description

Mesothelin is a 40 kDa glycosyl-phosphatudylinositol-anchored glycoprotein cleaved from a 71kDa precursor protein encoded by the human mesothelin gene. Mesothelin is present on the surface of normal mesothelial cells.1 Although the function of mesothelin is unknown, it is overexpressed in a wide variety of cancers including mesothelioma, pancreatic ductal adenocarcinoma, and ovarian carcinoma.1-6 Mesothelin has proven to be a valuable marker for pancreatic ductal adenocarcinoma due to its strong reactivity in tumor tissue and absence in normal pancreas.1, 3-4 Metastatic renal cell carcinoma can present clinical patterns that mimic primary mesothelioma, pancreatic ductal adenocarcinoma, and ovarian carcinoma.2, 4-6 Mesothelin has demonstrated utility in the differential diagnosis between these primary tumors and corresponding metastatic renal cell carcinoma within the context of an antibody panel.4-6

Both mesotheliomas and renal cell carcinomas can present a wide variety of morphological patterns. Because of this, renal cell carcinomas that metastasize to the pleura and lung may be confused with mesotheliomas. The aim of the present study was to

Mesothelin is a cell surface antigen of unknown function that is strongly expressed in mesothelial cells. Although it was reported in 1992 that immunostaining with the K1 anti-mesothelin antibody could be very useful in distinguishing between epithelioid mesotheliomas and pulmonary

To determine whether PAX2 and mesothelin immunohistochemistry add additional diagnostic value in discriminating between pancreatic metastasis of renal clear cell carcinoma (PMRCC) and primary ductal adenocarcinoma of the pancreas (PDAC). We retrospectively collected tissue from PMRCC and PDAC. Eleven cases

Mesothelin, a cell surface glycoprotein present on normal mesothelial cells, has been reported to be expressed in pancreatic adenocarcinomas. We conducted this study to fully characterize mesothelin expression in surgically resected, formalin-fixed, paraffin-embedded tissue specimens of 18 pancreatic adenocarcinomas, 9
