Abstract
We report two cases with elastofibroma dorsi, a 58-year-old man and a 60-year-old man. Both had a tumor of the subscapular region and severe back pain. Chest CT showed masses with a low density area. Chest MRI revealed masses with low signal intensity and interspersed areas of high signal intensity on T1 and T2 weighted spin echo sequences. They were diagnosed as elastofibromas and the masses were excised. Histological examinations revealed increased collagenous and elastic fibers with elastic van Giesson staining. An elastofibroma was thus diagnosed in both cases. There have been no symptoms or signs of recurrence since surgery.
