Elastofibroma: a subscapular mass

A large mass protruded from beneath the inferior angle of each scapula of a 69-year-old man when he adducted and elevated either arm 90° at the shoulder. The tumor is situated under the inferior angle of the scapula when the arm and scapula are in the neutral position. A chest computed tomography scan with contrast showed bilateral soft-tissue opacities below each scapula. The radiologic diagnosis of a typical subscapular elastofibroma was confirmed by core-needle biopsy of each mass. The radiologic and clinical diagnosis and surgical treatment of this benign soft-tissue tumor are discussed.
