Bilateral Elastofibroma

Abstract

Elastofibroma, or elastofibroma dorsi as it was first described, is an uncommon tumor-like process that characteristically appears as an ill-defined mass in the infrascapular region of elderly patients. This lesion can occur bilaterally and may appear asynchronously. The occurrence of elastofibroma in other anatomic sites has been reported, although with much less frequency. Elastofibromas display typical diagnostic histologic, cytologic, and electron microscopic features. The use of magnetic resonance imaging can lead to a presumptive diagnosis in elderly individuals with suprascapular lesions. It is important to differentiate this lesion from other soft-tissue lesions, such as sarcomas and desmoid tumors. This study presents a case of bilateral elastofibromas in a 72-year-old man and a review of the literature.
