The First-Reported Presentation of Quadruple Locations of Elastofibroma Dorsi: A Case Report and Review of the Literature

Elastofibroma dorsi (EFD) is an uncommon benign tumor of mesenchymal origin that usually occurs in the subscapular region. Bilateral and triple EFD are frequently reported in the literature but cases with more lesions have never been described. Our patient is a 50-year-old female with quadruple locations of bilateral suprascapular and subscapular EFD who presented with left shoulder pain and swelling over the affected area. Clinical presentation, computed tomography (CT) and magnetic resonance imaging (MRI), and biopsy were consistent with EFD. Therapeutic excision was performed and successfully alleviated the patient’s discomfort. This report presents the first case of quadruple locations of EFD and highlights the value of MRI in the diagnosis of EFD, especially when there are multiple masses with indistinct margins are deeply located in the chest wall.
