Desmoid-Type Fibromatosis Associated with Silicone Breast Implants

ABSTRACT

Desmoid-type fibromatosis (extra-abdominal desmoid tumor) arising in the breast is a rare benign disease entity, accounting for 0.2% of all breast tumors. The etiology of mammary fibromatosis is unknown, but has been reported to be associated with genetic factors, hormonal effects, Gardner syndrome, breast trauma or surgery, and breast implants. Fibromatosis associated with breast implants is extremely rare, and only 34 cases have been reported so far. We report the ultrasonographic, computed tomographic, and pathologic findings of breast fibromatosis in a 29-year-old woman, who underwent bilateral augmentation mammoplasty with silicone implants.
