[Retrospective analysis of 6 cases of elastofibroma dorsi].

Elastofibroma dorsi is a benign lesion of fibroelastic tissue. It often presents bilaterally, is frequently localized to the subscapular region, and is more common in middle-aged and elderly women. The pathogenesis is still unclear but it has been suggested to involve reactive, degenerative, or neoplastic processes. We present a retrospective study of the findings from 6 patients with elastofibroma dorsi. Elastofibroma should be included in the differential diagnosis of subcutaneous scapular tumors, as it is a benign lesion that only requires surgery when associated with symptoms or the lesion is extensive. Noninvasive techniques such as ultrasonography, computed tomography, and, above all, magnetic resonance imaging, may be sufficient to guide diagnosis. The results of histology and imaging are closely correlated, so the need for unnecessary biopsy and surgery may be avoided.
