Demonstration of Ductal Carcinoma in situ with Microcalcifications in a Patient with Augmentation Mammoplasty by Free Silicone Injection

Free liquid silicone injections were used for breast augmentation in the 1950s and 1960s. Patients who received these breast silicone injections are now at the age of high breast cancer risk, but breast masses in such patients are difficult to detect by clinical examination and imaging studies. Ultrasonography may be affected by silicones, but lesions superficial to the silicones can still be detected. Here, we report one patient who received silicone injection 35 years ago when she was 18 years old. Ductal carcinoma in situ with clustered multiple microcalcifications was noted on ultrasound and confirmed by histopathologic examination. Surgery was performed and there was no evidence of recurrence 20 months after operation.
