Elastofibroma is an uncommon fibroelastic tumor-like lesion which usually presents in a characteristic area between the lower portion of the scapula and the chest wall, lying deep to the latissimus dorsi and rhomboid major muscles. It appears almost exclusively in elderly individuals and is associated with history of repetitive tissue injuries. It has pathognomonic histopathologic findings. Although the lesion has previously been defined as a reactive process, its true etiology remains unknown. Based on clinical manifestations and correlation with imaging studies, a presumptive diagnosis of elastofibroma can be made in order to avoid an unnecessary surgery. Here we report a case of elastofibroma in a typical location and present a review of the literature behind its pathogenesis.
弹力纤维瘤是一种罕见的纤维弹性肿瘤样病变，通常出现在肩胛骨下部与胸壁之间的特征性区域，位于背阔肌和大菱形肌的深面。它几乎仅见于老年人，且与重复性组织损伤史有关。它具有特征性的组织病理学表现。尽管该病变以前被定义为一种反应性过程，但其真正病因仍不清楚。根据临床表现并与影像学研究相结合，可以做出弹力纤维瘤的初步诊断，以避免不必要的手术。在此，我们报告一例典型部位的弹力纤维瘤病例，并对其发病机制的相关文献进行综述。
