Large Desmoid Tumor in the Setting of Prior Cosmetic Breast Augmentation.

Desmoid tumors of the breast are rare, comprising 0.2% of all breast tumors. They may be locally invasive but do not metastasize. The etiology is multifactorial including surgical trauma in the setting of prior cosmetic augmentation breast implants. We submit a case of a large desmoid tumor in the breast following silicone implant placement three years prior to patient presentation. The patient was treated with wide local excision to negative margins and implant exchange. A follow up breast magnetic resonance imaging at 3 and 6 months did not detect a recurrence thus far.
