Mammary sarcomas are uncommon tumors. When tumors like malignant cystosarcomaphyllodes and metaplastic carcinoma, where malignant cartilaginous areas may be present, are excluded, only nine cases have been reported to date.We report another case of primary chondrosarcoma of the breast here. A 24-year-old Mediterranean woman presented with a painful mass in the right breast and a physical examination revealed a palpable mass. An incisional biopsy was performed and primary chondrosarcoma was diagnosed based on histological examination. Our patient underwent a mastectomy. A preoperative clinical and cytological diagnosis of chondrosarcoma, even though possible in a few cases, is usually not attained due to its similarclinical behavior with other breast tumors.
Le carcinome métaplasique du sein est une entité rare et bien individualisé par l'OMS. Il représente moins de 1% des cancers invasifs du sein et constitue un groupe tumoral hétérogène soit purement épithélial soit à doublecontingent épithélial et mésenchymateuse. Le carcinome métaplasique avec différenciation osseuse extensive est très rare. Il représente 0.2% des carcinomes du sein. Nous rapportant un cas exceptionnel d'un carcinome métaplasique du sein avec différenciation osseuse extensive chez une patiente de 53 ans. A travers ce cas et une revue de la littérature, les caractéristiques anatomo-cliniques, radiologique, thérapeutiques et évolutives seront discutées.
