Abstract
Extra-abdominal desmoid tumor is a rare soft tissue tumor that is histologically benign, but may behave aggressively. This case report specifically describes the clinical, radiographic, and pathologic features of 27 year-old female who experienced a post-surgical recurrence of fibromatosis of the chest wall over a two-year period of time secondary to previous inadequate excision. The fibromatosis was found to be involving the lower-inner quadrant of her right breast and causing worsening pain. A surgical management strategy was successfully undertaken.
