We report a locally advanced elderly breast carcinoma with skin invasion. The patient was a 96-year-old woman who had a breast lump. The palpable tumor was 3 .5 cm in diameter. Ultrasonography revealed a low echoic mass. A core needle biopsy for the breast tumor led to a diagnosis of an invasive ductal carcinoma positive for estrogen receptor and progesteron receptor, and negative for HER2/neu protein expression. She underwent a tumorectomy including the cancer invasive skin by local anesthesia. Because her respiratory function was unbearable to perform a muscle-preserving mastectomy with general anesthesia. The surgical margins of the resected specimen were negative. The clinicopathological stage, according to the UICC-pTNM classification, was Stage III C (T4b, N0, M0). After the operation, she was administered aromatase inhibitor. The patient has been well and remained disease-free during a follow-up period of 3 years. The surgical excision with local anesthesia was useful for locally advanced super senior breast cancer patients who were impossible to perform general anesthesia by various kinds of factors.
