Desmoid Tumor Following Augmentation Mammoplasty with Silicone Implants

A desmoid tumor (also known as aggressive fibromatosis) is a rare benign lesion that is characterized by fibroblastic proliferation from the connective tissue of the muscle and its overlying aponeurosis of fascia. "Aggressive fibromatosis" is the term used to describe a marked increased in cellularity and aggressive local behavior [[1]]. Desmoid tumors are characterized by a clinical course that ranges from locally inert to aggressive and destructive forms [[2]]. Although the mechanisms that affect the development, regulation, and growth of desmoid tumors are currently unknown, numerous factors, such as trauma history, hereditary background (e.g., familial adenomatous polyposis), and the hormonal environment are strongly associated with the development of desmoid tumors [[1] [3]]. Desmoid tumors account for 0.03% of all neoplasms and 0.2% of all breast tumors. There are few case reports describing implant-associated breast desmoid tumors in the literature [[4]], and no studies associated with breast implants have been reported in Korea. We report here a case of a desmoid tumor that developed following augmentation mammoplasty and describe our experience of treating this case.
