Qiao's Pathology: Granular Cell Tumour of the Breast
Microscopic photo showing tumor cells are positive for S-100 immunohistochemical (IHC) stain with diffuse nuclear and cytoplasmic staining. S-100 protein is a family of low molecular weight protein found in vertebrates characterized by two calcium binding sites of the helix-loop-helix ("EF-hand type") conformation. There are at least 21 different types of S100 proteins. The name is derived from the fact that the protein is 100% Soluble in ammonium sulfate at neutral pH.
