Chondrosarcomas usually arise in the pelvis or bones of the trunk, but rarely primary chest wall (rib) chondrosarcomas are also noted. We report the case of an 18-year-old female, who presented with left breast mass. On mammography and Ultrasonography (USG), possibility of giant fibroadenoma with cystic changes was given. On Fine Needle Aspiration Cytology (FNAC) and trucut biopsy of the mass, a diagnosis of pleomorphic adenoma was given. However, during resection it was found to be arising from left 4th rib, breast parenchyma was uninvolved and pushed to a side by the mass. Grossly, the mass was capsulated, lobulated and grey white measuring 17×13×10 cm. On cutting, it had a glistening bluish grey colour. On histology, a diagnosis of chondrosarcoma was given.
