Bilateral and atypical localized elastofibroma dorsi in a patient with shoulder and back pain: A case report

Abstract

A 61-year-old woman presented with localized back pain at the left inferomedial border of the scapula and left shoulder pain. On physical examination, a soft tissue mass was detected on the left scapula. Magnetic resonance imaging showed a mass at the left suprascapular region and another mass in the left infrascapular region. A Tru-Cut biopsy of the lesion at the left suprascapular region was obtained due to atypical localization. Pathological examination was consistent with an elastofibroma. During wire-marking, another mass was detected at the right infrascapular region. Three mass lesions were excised on consecutive operations. During follow-up, the patient reported reduced shoulder and back pain.
