Vertebral plasma cellular osteomyelitis

Abstract

Plasma cellular osteomyelitis is a chronic recurrent, unifocal or multifocal inflammatory disorder, which has an unknown aetiology. The infectious focus or foci may occur in different sites of the skeleton. This unusual clinical entity has been reported in over 200 cases in the relevant literature, but the involvement of the spine with plasma cellular osteomyelitis has not been reported before. Because of the rarity of this disease and the possible difficulty in differentiating plasma cell osteomyelitis, both clinically and histopathologically from the other similar afflictions of the spine, we describe our case.
