Phyllodes tumors are rare fibroepithelial tumors that make up less than 1% of all breast tumors. Malignant phyllodes tumors are associated with a 25% incidence of distant metastasis, which is invariably fatal within 24 months. We report successful resection of a solitary pulmonary metastasis in the left chest in a 50-year-old woman 7 years after a right- sided mastectomy for malignant phyllodes tumor.
