1.1. Introduction: Elastofibroma dorsi (ED) is a benign, uncommon tumor, which appears in the subscapular and infrascapular region. Etiology is still under discussion. Total surgical excision is the optional treatment for symptomatic EFD. 1.2. Presentation of Case: A 48-year-old male patient presented with 2 years’ complaint of shoulder pain and paresthesia, mostly aggravated with shoulder movements and infrascapular swelling bilaterally.

Symptoms and significant discomfort from the surgical procedure was completely resolved within a few weeks’ interval from the operation. 1.3. Discussion: it is a rare tumor, and its etiology suspected to be due to repetitive trauma and still under question, image is the best method to diagnose it. 1.4. Conclusion: EFD is a benign soft tissue tumor, placed at infrascapular region, treated with total simple excision, biopsy is not needed
