Solitary plasmacytoma of the vertebral column. A report of 15 cases.
The clinical features and the treatment results of 15 patients with solitary plasmacytoma of the spine observed in a 28-year period (1950-1977) are reported. The signs at presentation were back pain in 4 cases and spinal cord compression in 11 cases. Three of these patients had paraplegia. Radiologically, the alteration encountered was an osteolytic lesion in all cases. The local treatment was radiotherapy in 11 cases and surgery plus radiotherapy in 4 cases. In 3 patients systemic chemotherapy was also employed. Seven patients are alive without signs of disease 3 to 9 years (mean 6 years) after diagnosis. Eight patients developed multiple myeloma in a period ranging from 1 to 8 years (mean 3.5 years). The relationship between multiple myeloma and solitary plasmacytoma of the spine, as well as the best treatment for the latter, are discussed.
