[Plasma cell and sclerosing osteomyelitis. A follow-up of 21 patients].

Plasma cellular osteomyelitis was seen in the metaphysis while sclerosing osteomyelitis affected the diaphysis of long bones. In only about 20% of both forms local bacteria were noted. The onset of symptoms was inconspicuous and both clinical and radiological signs were nonspecific. Curettment or resection usually cured the disease. In some cases, however, aggressive surgery was necessary. As to surgery and outcome sclerosing osteomyelitis appeared less riskful than plasma cellular osteomyelitis. Both forms apparently represent the same basic pathological condition.
