title: Localised myeloma with osteogenesis and Russell body formation.
abstract: A case of an osteosclerotic myeloma of the mandible is described. Bone formation took the form of prominent sunray spiculation and radiologically mimicked an osteosarcoma. No other well-documented solitary lesion of this type could be found in the English literature. In addition, this tumour contained an abundance of intracytoplasmic Russell bodies and also produced a paraprotein. The paraprotein peak disappeared after resection.
