The hair shaft made of a protein called keratin is tough and resistant to wear and tear. Eighteen amino acids make up the keratin of which the most abundant is the cysteine. It gives the hair much of its strength. The middle layer of the hair is the cortex. It is made up of polypeptide chains that are cross-linked with each other, by three different types of side bonds.
Of the keratin cocktail-positive tumors, 8/61 cases (13%) were focally positive for K7 (Figure 5). In many of these cases, contribution by perivascular smooth muscle elements cell could not be definitively ruled out. K1 was detected in 24/39 (62%) of cases, usually focally.f the peripheral schwannomas, only three of 22 were positive for GFAP and all were negative for AE1/AE3 keratin cocktail, so no further cytokeratins were evaluated on these tumors. Of the retroperitoneal schwannomas, 104/115 cases (90%) were positive for GFAP (14+) (Figure 3).
