Diffuse osteoporosis

Diffuse osteoporosis is one of the symptoms of myeloma. Myeloma (also known as plasmacytoma) is a malignant tumor that originates from plasma cells in the bone marrow and is a more common malignant tumor. There is a distinction between single and multiple, the latter is more common. Multiple myeloma, also known as multiple myeloma (MM), is caused by malignant changes in plasma cells with synthetic and secreted immunoglobulins. A large number of monoclonal malignant plasma cells proliferate and easily involve soft tissues. Metastases, but few lung metastases. More common in the spine, accounting for 10% of primary spinal tumors, more common in the lumbar spine. The prevalence of men and women over 40 is about 2: 1. Frequently occur in men over 40 years of age, and the most common sites are spine, ribs, skull, and sternum. X-ray bone examination: the affected bone shows a circular puncture-like defect, with the skull as a typical example. Diffuse osteoporosis and decalcification can also be seen.
