Multiple myeloma of the thoracic spine developed at the previous trauma site: case report.

The precise nature of the underlying plasma cell dyscrasias is not well understood. Even today, no causative factor has been found for this disease. It has been suggested that, several factors may act together in the development of this disease. This is a report of a 62-year-old man who initially had a T7 compression fracture and developed a multiple myeloma two years later at that site and at the adjacent vertebral level (T7-T8), respectively. Although the notion that trauma would initiate such a malignancy is speculative, the preceding trauma may be a causative factor in plasma cell dyscrasias.
