[Micro-molecular plasmocytoma: case report (author's transl)]

The histological diagnosis of an apparently solitary destructive bone lesion revealed a plasmocytoma, being suspected of generalized spreading. Thereupon performed radiological examination demonstrated multiple radiolucent skeletal lesions and supported this diagnosis. Although specific hematological and proteinchemical findings were not indicative in the first instance, a second scrutiny of protein rates succeeded to demonstrate Bence-Jones-Kappa and consequently this case could be classified as a multiple micro-molecular plasmocytoma.
