Concomitant right subscapular and left olecranon elastofibroma followed by inversion of the lesions: case report

Elastofibroma is a benign, poorly circumscribed, tumor-like condition involving, in the vast majority of cases, the subscapular region of elderly individuals, though isolated cases have been seen in the deltoid muscle, infraolecranon area, hip, thigh and stomach. It is characterized by accumulated abnormal elastic fibres and is generally regarded as a reactive process, an unusual fibroblastic pseudotumor. Multiple elastofibromas have been reported to occur in the scapula and olecranon and in the scapula and ischium, whereas literature reports of multiple elastofibromas in the same patient are rare. The case of concomitant, asynchronous double elastofibroma in the same patient is described. A 69-year-old woman presented with right subscapular and left olecranon swelling associated with pain and a clicking sensation during certain arm movements. Some months later the patient developed asymptomatic left subscapular and right olecranon swelling. All the lesions, which were subsequently diagnosed as elastofibromas, were removed.
