Elastofibroma dorsi: three cases of personal experience

Elastofibroma dorsi is a rare, slow growing, soft tissue lesion, which occurs mainly in elderly women, tipically located in the infrascapular region. This lesion is characterized by a poorly defined solid mass of fibroelastic and fatty tissue, enlarging into intermuscular spaces. Elastofibroma may simulate an aggressive behaviour, and differential diagnosis with malignant tumors is sometimes difficult. Surgical resection is generally recommended in symptomatic lesions or in the suspicion of malignancy. We report our experience of three cases of elastofibroma, two of which typically located in the infrascapular region and one located in the supraclavear fossa, atypical site never reported so far.
