A 68-year-old man had a painless, nontender lump in the right infrascapular region. An unenhanced computed tomography (CT) scan showed a soft-tissue mass attached to the scapula, causing muscular displacement. A similar, smaller mass was found on the left side. The appearance of the masses on CT scans was suggestive of infiltrating malignancy, but pathologic examination disclosed findings typical of elastofibroma. Biopsy is recommended in similar cases to exclude sarcoma.
