Elastofibroma dorsi: clinical and pathologic aspects of two cases.

Elastofibroma dorsi is a benign entity that occurs most often in the subscapular area in elderly women. It has been a subject of controversy whether elastofibroma is a true neoplasm or a reactive fibrous lesion that produces abnormal elastic fibers. A biopsy should be performed to rule out sarcoma in all cases, but definitive treatment only requires simple surgical excision. We report two cases of elastofibroma and discuss the most relevant clinical and pathologic aspects.
