Figure 3.
EMP involving the larynx (vestibular fold) with associated light chain amyloid (patient 7). (A) Tumor forming subepithelial amyloid is detectable in the Kongo red staining (om ×25). (B-C) Subepithelial mature plasma cells (B, om ×20) and amyloid depositions (C, om ×200) are present. (D-E) Plasma cells show expression of κ (D, om ×400) and remain negative for λ light chain (E, om ×400).
