Giant Chest Wall Hematoma Mimicking Elastofibroma Dorsi: A Case Report

wall are uncommon (1). In addition, hematomas on the thoracic wall are very rare (2), although there have been a few case reports about chronic expanding hematomas in the thorax (2-4). Yet to the best of our knowledge, a huge, rapidly growing hematoma of the chest wall at the same location as an elastofibroma dorsi has not been previously reported. We describe here a 63-year-old man who was without a history of trauma or a bleeding disorder and who presented with a huge, rapidly growing chest wall hematoma. He had a large mass in his right subscapular space and the computed tomography (CT) and magnetic resonance imaging (MRI) findings were similar to those of elastofibroma dorsi.
