Other pertinent negative immunostains include hematolymphoid markers (CD45, CD3, CD20, CD79a), myoid markers (smooth muscle actin (SMA), desmin), vascular markers (CD31, CD34), epithelial markers (EMA, keratins), melanoma markers (melanA, SOX10, HMB45, S100), and other markers (ALK, CD30) [44,45]. This evidence concerns the gene SMN1 and melanoma.
