[Chest wall fibromatosis after mammary prosthesis implantation. A case report and review of the literature].

Desmoid tumour of the breast is a rare lesion. Only 9 cases in which the origin of the tumour was linked to a breast implant had been published up to 2004. We report a case of aggressive fibromatosis which developed on the thoracic wall two years after implantation of a mammary prosthesis. This tumour was locally aggressive. Radical surgery is the treatment of choice and in this case required a wide surgical resection, including removal of the chest wall, to gain control. The application of adjuvant radiation therapy is controversial.
