An extramedullary mucosal plasmocytoma of the middle ear and mastoidal mucosa, which was antrotomized, is described. The diagnosis has been secured in cytological, histological and postmortem findings. The plasma cell infiltration was confined to the mucosa. In the operational region there was no histological indication of an affection of the bones. The X-ray picture did not show any safe osteological changes in the remaining skeletal system either. There existed, however, all clinical symptoms of a diffuse plasmocytoma with corresponding changes in the bone marrow, paraproteinemia, proteinuria without Bence-Jones protein, anemia and progredient development up to the exitus due to pneumonia. Contrary to the opinion that extramedullary plasma cell tumors represent a pathological picture of their own, it is held that these plasmocytomas also belong to the category of diffuse myelomata, distinguishing themselves by a peculiar progressive form.
