Desmoid Fibromatosis of the Breast: 1 Case Report and Review of the Literature

Aggressive fibromatosis (desmoid tumour) of the breast is a rare tumour thataccounts only for 0.2% of primary breast tumours. This is a benign mesenchymal tumour that develops from muscular fasciae and aponeuroses. It is characterized by its local evolution and its tendency to relapse without metastasizing. Wide radical resection should be attempted whenever possible. Positive margins at resection and reoperation are associated with a high risk of local recurrence. The role of radiotherapy and of medical treatments especially antiestrogens remains unclear.
