Breast Implant Capsule-Associated Squamous Cell Carcinoma: Report of 2 Patients

Breast implant augmentation is a low-risk procedure with few life-threatening complications. Capsular contracture and rupture/leakage of the implant are the most common complications encountered. Malignant breast implant augmentation-associated lesions are rare, with anaplastic large cell lymphoma being the most common. Squamous cell carcinomas associated with breast implant augmentation are exceedingly rare, with only eight patients reported. Breast implant capsule-associated squamous cell carcinoma occurs in patients with long standing breast implant augmentations (>11 years). We report two additional patients with breast implant capsule-associated squamous cell carcinoma. Review of the literature reveals that invasion beyond the breast implant capsule into the adjacent tissue by the squamous cell carcinoma appears to have negative prognostic implications, and possibly warrants close clinical follow-up.
