Elastofibroma of scapula: a case report and literature review.

Elastofibromas are benign soft tissue tumors. They occur mostly in the infrascapular region between the thoracic wall, the serratus anterior and the latissimus dorsi muscle, with a prevalence of up to 24% in the elderly. The etiology of this lesion remains uncertain and is a source of ongoing debate. We herein report a 54-year-old female patient, manual worker who presented with bilateral subscapular slow growing tumors for 7 months. Physical examination showed two masses of 4 cm in diameter on the right, and 8 cm on the left, both located inferior to the inferior margin of the scapula. They were more or less firm and mobile on palpation. Computed tomography scan showed large fusiform subscapular soft tissue heterogeneous solid masses with linear areas of low density secondary to fat. The lesions measured 5 cm × 4 cm on the right side and 8 cm × 8 cm on the left. Resection of the largest left tumor was achieved. Macroscopic and histological findings were consistent with elastofibroma.
