Elastofibroma dorsi (ED) is a soft tissue tumor found in the subscapular region. The pathogenesis of ED is unclear, but may involve a regenerative or reactive hyperproliferation due to mechanical microtrauma. Magnetic resonance imaging (MRI) is preferred to diagnose ED and complete excision is curative. When bilateral, subscapular masses are identified in the elderly patient and MRI characteristics are typical, biopsy and excision can be avoided. Symptomatic EDs should be excised, and recurrence is rare. Three hundred and thirty cases of ED have been reported since 1980. Fourteen case series and 43 isolated case reports involved 263 women and 67 men (F:M ratio = 3.9:1), with a mean age of 62 years (range 6-94 years). Bilateral ED was present in 164 patients and unilateral ED in 157. The reported prevalence in the elderly population ranges from a minimum of 2% to a maximum of 24%.
背部弹力纤维瘤（ED）是一种位于肩胛下区域的软组织肿瘤。ED的发病机制尚不清楚，但可能涉及由于机械性微创伤导致的再生性或反应性过度增殖。磁共振成像（MRI）是诊断ED的首选方法，完整切除可治愈。当在老年患者中发现双侧肩胛下肿块且MRI特征典型时，可避免活检和切除。有症状的ED应切除，复发罕见。自1980年以来已报告330例ED。14个病例系列和43篇孤立病例报告涉及263名女性和67名男性（女性与男性比例=3.9:1），平均年龄62岁（范围6-94岁）。164例患者为双侧ED，157例为单侧ED。老年人群中报告的患病率最低为2%，最高为24%。
