Elastofibroma
Synonyms
Definition
A benign lesion characterized by abundant abnormal elastic fibers.
Clinical Features
Incidence
It is considered a rare lesion, although the exact incidence is unknown as many cases represent incidental findings (Hisaoka and Nishio 2013).
Age
It tends to affect elderly patient, with a peak in the seventh and eighth decades of life.
Sex
Females are more frequently affected than males (Nagamine et al. 1982).
Site
It generally arises in the soft tissue under the scapula, where it is supposed to be generated after repeated frictions between the scapula and the thoracic wall, with subsequent degeneration of the elastic fibers. Rarely, it can occur in other parts of the thoracic wall, in the extremities, limb girdles, gastrointestinal tract, or other viscera. The lesion can be bilateral or rarely multiple (Hisaoka and Nishio 2013).
Treatment
Simple surgical excision is curative.
Outcome
It is a benign lesion. Local recurrence can occur, after incomplete...
