[Neoplasias of the scapula--rare causes of chronic shoulder-arm syndrome].

The diseases most frequently resulting in a chronic shoulder-hand syndrome are definitely of a post-traumatic nature and are later - after a varying period - often combined with degenerative changes. The tendency to injury is enhanced by the particularly great mobility of the shoulder joint. Inflammatory changes - e.g. of bacterial, rheumatic origin - are much rarer. The authors present two patients with rare neoplastic lesions in the region of the shoulder-blade and show how the disease was identified via various differential diagnostic methods.
