Bilateral elastofibroma dorsi

Elastofibroma dorsi was diagnosed in a 76-year-old woman with bilateral subscapular tumor masses and a 3-year history of recurrent, right-sided scapular pain. A bilateral tumor extirpation was performed and the patient left the hospital free of symptoms 10 days later. We suggest that both constant trauma with resulting excessive elastin production and collagen degeneration might play a major role in the pathogenesis of this rare proliferative lesion.
