Immediate Two-stage Breast Reconstruction after Mastectomy and Filler Removal in a Patient with Breast Cancer following Augmentation with Copolyamide Fillers.

Breast augmentation using copolyamide fillers, such as Aquafilling, is associated with various complications, leading to an increasing consensus against their use. However, the occurrence of breast cancer in patients who have undergone augmentation with fillers has been rarely reported. The management of such cases, particularly in terms of breast reconstruction, presents unique challenges owing to the presence of filler materials. We report the case of a patient with breast cancer who underwent immediate two-stage implant-based breast reconstruction after breast augmentation with Aquafilling. No capsular formation was observed around the tissue expander during the second reconstruction procedure. To prevent implant migration, the normal tissue of the marginal pocket was identified and sutured. However, caudal migration of the implant still occurred. This case highlights the need for improved surgical techniques to stabilize silicone breast implants effectively. Further research is warranted to understand the long-term implications of copolyamide fillers on breast reconstruction outcomes.
