Immunohistochemistry is not usually of value in distinguishing between salivary gland tumors, although differential expressions of cytokeratins, S-100 protein, GFAP, CD117, MCM2 (minichromosome maintenance proteins), and MYB may be of help.
The tumor cells were immunohistochemically positive for CK7, CD117, and Hale's colloidal iron.
These immunohistochemical studies included reagents specific for CD3, CD11c, CD20, CD33, CD43, CD68, CD117, CD163, lysozyme, and myeloperoxidase.
Neuropilin-1 mRNA level by real-time PCR showed a positive significant correlation with peripheral blood blast percentage and CD117 and a negative correlation with hemoglobin level in de novo AML patients.
