Breast augmentation is the most common cosmetic surgery in the United States. Squamous cell carcinoma (SCC) of the breast raises suspicion of possibly metastatic origin. Here, we report an unusual case of implant-associated SCC of the breast post silicone gel breast implant. The patient is a 46-year-old female with SCC of the breast. She initially had silicone gel breast implantation for breast augmentation in 1995. She had multiple revisions due to swelling and hardening. In 2016, she underwent bilateral prosthesis explantation and bilateral capsulectomy. The pathology demonstrated a 4-cm tumor that was moderately differentiated invasive SCC. On slide review, it was noted that there was squamous epithelization of the implant capsule with benign squamous epithelium on both sides. She received external beam radiation to the right breast; no adjuvant chemotherapy was offered due to the rare histology and paucity of data. Follow-up within a year showed metastasis to the liver, lungs and retroperitoneum. She was admitted and ultimately transferred from the medical intensive care unit to the palliative care unit for comfort care. She expired of her disease in July 2017.
