title: Metastasis of humeral osteosarcoma to the contralateral breast detected by 99mTc-MDP skeletal scintigraphy.
abstract: A rare case of osteogenic sarcoma (OGS) of the left humerus metastasizing to the right breast is presented. This lesion was detected by serendipitous observation on (99m)Tc-MDP skeletal scintigraphy that demonstrated a rounded focus just outside the skeletal outline of the right chest. The focus remained at a similar location on repeat postwash view. Clinical examination revealed a breast mass corresponding to the site of uptake, and a biopsy of this mass revealed it to be a metastasis of osteogenic sarcoma. The present case demonstrates a rare site of metastasis from OGS of the left humerus to the contralateral breast and hence is reported here as an unusual case vignette.
