Abstract
-
We report a case of primary osteosarcoma of the breast which is rare and
exhibits poor prognosis. A 52 years-old-woman was admitted with rapidly growing
right mammary mass. A huge lobulated dense mass with speckled calcifications,
suggesting malignancy, was observed on mammography. She underwent a radical
mastectomy. Grossly, the mass measured 16 14 6 cm and showed grayish white hard
lobulated tissue with focal hemorrhage and necrosis. Light microscopically, the tumor
was confirmed as an osteosarcoma devoid of any epithelial components. In postoperative
whole body bone scan, there was no evidence of the other malignancy. To the best of
our knowledge, the present case is the first report of primary osteosarcoma of the
breast in Korea.
