Elastofibroma dorsi. Report of five cases and review of the literature

Five cases of elastofibroma dorsi are described. The location of the lesions (bilateral in one case) was typical, in the thoracoscapular region. In the first case the diagnosis was established by biopsy; in the remaining cases the diagnosis was suspected based on clinical and magnetic resonance imaging findings and was confirmed by histopathological study after surgical excision. Although these lesions are benign, histological study is advisable to establish a differential diagnosis with malignant neoplastic processes.
