Application of two different clones of vimentin to the diagnosis of salivary gland tumors.
With the evolution of IHC techniques, a broad range of antibodies have become available to diagnostic immunohistology. The authors observed different expressions of vimentin in salivary gland tumors using two clones of this antibody. This study was undertaken to show these differences comparing the immunoexpression of two clones of vimentin (V9 and Vim 3B4, DAKO, Carpenteria, CA) using 10 pleomorphic adenomas, 10 adenoid cystic carcinomas, and 4 epithelial/myoepithelial carcinomas of the salivary glands. The V9 clone of vimentin was much more efficient in demonstrating the myoepithelial cells in the different tumors studied. The Vim 3B4 clone was capable of detecting some myoepithelial cells, the plasmacytoid or modified myoepithelial cells in the pleomorphic adenoma, but was very weak in epithelial/-myoepithelial carcinomas. The difference between the two clones studied is a warning that pathologists need to know the specificity and sensitivity of the reagent they are using.
