Elastofibromas (EFD) are rare benign soft tissue tumors that are almost always located at the inferior pole of the scapula, deep to the serratus anterior muscle. They are more frequent in elderly women. Their anatomical location and a distinctive clinical symptom distinguish them from malignant soft tissue tumours.

They can usually be diagnosed on the basis of their imaging characteristics. Despite their low incidence, these lesions should be kept in mind to differentiate them from malignant tumours and to avoid unnecessary biopsies and wide or radical surgery. We present the case of a 55-year-old woman who complained of chronic pain related to a right infrascapular mass. She was diagnosed by magnetic resonance imaging (MRI) of bilateral subescapular tumor masses both compatible with elastofibroma. She underwent resection of the symptomatic right lesion through an amyotomical approach.
