[Clinical picture and radiology of plasmacytoma. Analysis of 116 cases].

The primary clinical, laboratory, and radiological findings of 116 patients with plasmacytoma were analysed and correlated. Skeletal findings could be seen on the radiograms of 105 of 116 patients (= 90.5%): All of the five patients with solitary plasmacytoma and 96 of 111 patients with multiple myeloma showed osteolyses; four of 111 patients with multiple myeloma showed sole osteoporosis. The leading clinical symptom was skeletal pain; whenever the pain was located in the spine skeletal findings were evident. Paraproteinaemia turned out to be the most important laboratory finding. Its proportion depended on the grade of radiological findings.
