Elastofibroma dorsi: review of 4 cases.

Elastofibroma dorsi is a benign, uncommon fibroelastic tissue condition, more common in women after the fifth decade of life. It is usually located in the subscapular region, and can sometimes be bilateral. We present 4 patients, between 53 and 73 years of age, with this disease. It is often an asymptomatic lesion that can manifest, even at its apex, with mild pain when moving the scapula. All our patients had pain.The diagnosis is based on clinical findings and imaging studies, especially ultrasound, computed tomography, and nuclear magnetic resonance. The biopsy is reserved for patients who have no characteristic signs on imaging. In our series, surgical excision was necessary in one of the patients, and in the others, clinical and imaging studies allowed us to arrive at a definitive diagnosis.
