Report of Two Cases of Myeloma

Abstract

I have experienced two cases of myeloma in young adult.
1. Male, aged 24 years, was invaded only his fourth lumbar vertebral body. His general condition was good; Bence-Jones's protein in urine was positive. At laminectomy for treatment of compression myelitis, tumor originated from the fourth lumbar vertebral body was found, which was determined histologically as plasma-cytoma. The clinical course was benign.
2) Male, aged 19 years, was invaded his ribbs, sternum and spine. No anemia and Bence-Jones's protein were proved and the clinical course showed malignant nature. The sort of cells consisting tumor could'nt exactly determine by autopsy, however, it can be said to originate from marrow tissue.
