CT scan of the patient with the extramedullary multiple myeloma of the larynx. The tumor displays as a solid mass in the area of the right vocal cord (red asterisk). The lumen of the larynx and therefore also the airway is extremely narrowed (red arrow) (a). The thyroid cartilage on the right side seems to be significantly thinned out (red circle) (b).

The CT scan (Figure 1) showed now a tumor of the right vocal cord extending to the right piriform sinus.
In HE staining, tight lymphoid infiltrates can be seen. The cells have large nuclei, and they are irregularly constructed (a). Immunohistochemical staining reveals a positive expression of CD10 (b). Magnification: 40x; scale bar: 50 mum.
