A 79-year-old woman was aware of a mass in her left breast and visited our hospital. On palpation, a 6 cm red tumor was observed in the left breast ABE area. She had previously undergone breast augmentation by silicone injection into both breasts. Ultrasonic examination revealed a slightly low-echoic, nonuniform mass image between the non-echo structures of silicone, and a core needle biopsy showed invasive carcinoma. MRI showed a contrast effect in the tumor and an axillary lymph node. Thoracoabdominal CT showed an enlarged tumor occupying the left breast with partial calcification. No distant metastasis was apparent. The patient underwent a total mastectomy with sentinel lymph node biopsy. Pathological analysis revealed a tumor in the silicone granuloma ; the tumor cells were similar to ones found in the needle biopsy. Silicone contamination was also found in the sentinel lymph node, but metastasis was not found. We experienced a breast cancer patient who had silicone granuloma after breast augmentation.
