[Osteogenic sarcoma of the breast].
A ball-shaped lump, 6 cm in diameter, showing the structure of extraosseous osteogenic sarcoma, was removed from the left breast of a 59 year old woman. This extremely rare breast tumour was seen developing indepedently, i. e. enconnected with any other epithelial, mesenchymal or mixed tumour as is more often the case. It is usually included in the group of stromal sarcomas of the breast. In addition, there was also dysplasia and a small focus of lobular carcinomas in the mammary gland.
