[A case of the breast cancer metastases to skin treated with local radiotherapy was effective].

A case was a 78-year-old woman. We detected a precordial tumor by palpation in January 2007. The patient left it untreated for a while. She then came to see us as the tumor had grown enlarged. In local findings, the precordium midline showed a non-elastic tumor of 2 cm in size. Biopsy revealed a possibility of breast cancer metastases. Mammography and the breast echography did not show any anomalies. Histopathology specific immune-staining was CK7, CEA positive, ER (+), PgR (+). The diagnosis was latent breast metastasis. Radiotherapy was performed and irradiated a total dose of 66 Gy. Our judgment was cCR in the post irradiation. After 2 years from the radiotherapy, there was no recurrence or metastases confirmed until today. In a breast cancer treatment, radiotherapy will be performed for the purpose of local control. However, we report here our experience with an unusual cCR judgment of more than 1 year for reference.
