Abstract
1. A case of solitary plasmocytoma of bone with survival for twenty-two years after amputation is described.
2. Recent follow-up of a previous tumour reported from this department by Stewart and Taylor in 1932 has shown survival for thirty-five years after amputation.
3. These two instances of long survival, together with three culled from the literature, substantiate the hitherto doubted concept of a true solitary plasmocytoma of bone.
