Excision of recurrent bilateral elastofibroma dorsi: A rare image

A 60-year-old woman was admitted to our hospital due to bilateral dorsal swelling and pain. She had undergone surgery at the swelling sites for bilateral elastofibroma in another institution 10 years previously. Bilateral subscapular swelling and operation scars were detected on physical examination. Computed tomography of the thorax obtained at another institution revealed mass images in bilateral subscapular fields (Figure 1). Concurrent bilateral excision was performed under general anesthesia in a prone position. The two masses measuring 16 × 10 × 3 cm and 10 × 8× 3 cm were excised consecutively (Figure 2). Histopathology showed elastofibroma dorsi (Figure 3). No complication developed and the patient was discharged on the fifth postoperative day. Complete resection of elastofibroma dorsi is of great importance for prevention of recurrence. Rarely, a concurrent operation should be performed in cases of bilateral recurrent elastofibroma dorsi, depending on the general condition of the patient. OPEN IN VIEWER
