Purpose: The pathological differential diagnosis of breast tumors presenting an osteosarcoma-like histological picture. Material and Methods: Light microscopic study of H & E stained sections, with cytokeratin, epithelial membrane antigen, vimentin, oestrogen and progesteron receptor immunohisto chemistry. Result and conclusions: The correct diagnosis of osteosarcoma-like breast tumors is important in view of making therapeutic decision. Carcinosarcomas and metaplastic carcinomas prefer lymphatic spread, while true osteosarcomas and malignant phylloid tumors usually metastasize first to the lung via the bloodstream. Malignant phylloid tumors generally have a more favourable prognosis.
