Remodelling acquired chest wall deformity after removal of a large axillary lipoma.

Acquired chest wall deformities are rarely encountered. Most of them result from pathologic process within the thorax, chest wall disease, iatrogenic deformities or post-traumatic. We present a case of a huge axillary mass deforming the chest wall. Surgery treated a well-encapsulated lipoma. Six months postoperatively, the chest wall restored to normal shape with active respiratory physiotherapy. This is the first reported case of spontaneous 'remodelling' of the chest wall without surgery.
