Metastatic osteosarcoma to the breast: a rare case.
Osteosarcoma is the most common malignant bone neoplasia and metastasizes mainly to the lung. Breast metastasis is an extremely rare event and poorly reported in the literature. We present a case of a 51-year-old patient, with a past surgical history of thigh osteosarcoma presented metastasis to the right breast and lung. She underwent the metastasis resection and later abandoned the treatment. Metastasis of osteosarcoma to the breast is an extremely rare event, but this diagnosis should be considered when meeting patients with a large breast nodule and a past history of osteosarcoma.
