Elastofibroma: a rare case report and review of the literature

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.
