Breast chondrosarcoma [Chondrosarcome mammaire]

摘要

Sarcomas of the breast are extremely rare, with less than 0,1% of all malignant tumours of the breast. The primitive chondrosarcoma of the breast is extremely rare. Only six cases were reported in the literature. We report the case of a 53-years-old woman with a nodule of the right breast, which appeared three months before diagnosis, and quickly increased in volume; an axillary adenopathy on the same side was also detected.The mammography showed a large opacity of almost the entire right breast and a second opacity in the axilla. An abdominal echography showed hepatic secondary localizations. A surgical biopsy was carried out and the morphological and immunohistochimical studies favoured the diagnosis of chondrosarcoma. Primary chondrosarcoma of the breast is extremely rare. However, the diagnosis cannot be retained before eliminating the possibility of a carcinosarcome or a phyllode's tumour with chondro?de differentiation. Morphology together with immunohistochimy allows the differential diagnosis of these tumours. The treatment is surgical, but in the event of metastases, the treatment remains problematic because of chimio-and radioresistance of these tumours.
