title: Breast cancer cutaneous metastasis at core needle biopsy site.
abstract: Cutaneous metastasis from breast cancer can occur by direct invasion, lymphatic and vascular spread as well as iatrogenic implantation. Metastasis that occurs by iatrogenic implantation after needle biopsy is very rare but the potential risk must be considered. In this report, we describe a case of breast cancer cutaneous metastasis that occurred by iatrogenic implantation following core needle biopsy. A 53-year-old woman presented with a 1x1 cm sized erythematous nodule at the biopsy site after breast conserving surgery for primary cancer. Histopathological findings confirmed cutaneous metastasis. The possibility of this consequence must be considered when performing needle biopsies.
