ABSTRACT
Elastofibroma is a benign fibroproliferative tumor of unknown origin and pathogenesis. It usually appears in the subscapular or infrascapular area. It is extremely rare in the spinal area, and it is most common in middle-aged women. In most cases, it is asymptomatic. Its diagnosis is based on nuclear MRI, where it presents a homogeneous lesion, similar to the skeletal muscle, hyperintense in T1-weighted sequences and hypointense in T2-weighted sequences. This finding is confirmed with anatomical pathology tests, where it appears as a nonencapsulated lesion made up of wide collagen bands from connective tissue mixed with fat and muscle tissue. The treatment of choice is surgical removal of the lesion. We present a clinical case of elastofibroma, a benign and rare pathology with few described cases in the literature, in a patient with a previous dorsal lesion.
