Elastofibroma dorsi: Histologic and echographic considerations

Background: Elastofibroma dorsi is a relatively rare soft-tissue tumor of the elderly with typical localization to the subscapular area. To date, few cases have been reported in the dermatology literature. The differential diagnosis includes frequently observed subcutaneous neoplasms such as lipoma, fibrolipoma or more aggressive tumors. The diagnosis is made with histologic examination. Case report: We present a typical case of elastofibroma dorsi, studied with ultrasound investigation and color-power Doppler, and discuss the correlation with the histologic picture. Conclusions: Considering the strict correspondence between the characteristic histologic findings of elastofibroma and the specific ultrasound pattern, we believe that ultrasound investigation with color and power Doppler allows, in typical cases, a definitive diagnosis of elastofibroma.
