[Dorsi elastofibroma. About 14 cases, and review of the literature]

Elastofibroma dorsi is a benign tumor which usually occurs at the inferior angle of the scapula. We retrospectively reviewed 14 cases of elastofibroma dorsi, in nine patients. The patients were hospitalized in the departments of plastic surgery, orthopedic surgery or visceral surgery. Mean age was 67 years. The location of the lesions (bilateral in five patients) was typical, in the thoracoscapular region. Nine lesions were removed surgically, six shoulders were asymptomatic after surgery. Elastofibroma is a rare, slow-growing lesion. It occurs in connective tissue of the infrascapular region of elderly patients. The pathogenesis of the lesion still remains unclear. MRI and computed tomography are useful for assessment of elastofibroma dorsi, and can potentially help avoid the need for unnecessary biopsy and surgery, especially in the asymptomatic patient. It should be surgically removed only in symptomatic patients.
