Abstract: Breast desmoid fibromatosis (BDF) is a rare, locally invasive neoplasm that predominantly affects females.Although BDF is typically benign, it can infiltrate the rib cage, necessitating invasive surgical resection and complex chest wall reconstruction.While there have been reported cases of BDF in association with silicone breast implants, cases requiring rib resection and chest wall reconstruction following augmentation mammoplasty are exceedingly rare.Here, we present two such cases and the reconstructive challenges involved.Two women, both under 30, developed invasive BDF within three years of bilateral subpectoral silicone breast augmentation.Both presented with rapidly enlarging chest wall masses detected through self-examination.Imaging revealed bulky, aggressive tumors infiltrating the pectoralis muscle and abutting the underlying ribs.In both cases, biopsies confirmed breast desmoid fibromatosis.Due to extensive chest wall involvement, surgical management included en bloc segmental rib resection and chest wall reconstruction with rib plating.Tissue expanders were placed as the first stage of breast reconstruction, preserving chest wall integrity and optimizing aesthetic outcomes.Given the rarity and infiltrative nature of BDF, early recognition and a multidisciplinary approach to surgical management are crucial.Surgeons should consider breast desmoid fibromatosis in the differential diagnosis of breast masses in patients with a history of silicone augmentation..
