[Breast chondrosarcoma: a case report and review]. / Chondrosarcome du sein: à propos d'un cas.

ABSTRACT

Sarcomas of the breast are relatively rare and account for 1% of all primary malignant tumors of the breast. Only 4 cases of pure chondrosarcoma of the breast have been published. We report an additional case in a fifty-seven-year-old woman. Histological and immunohistological characteristics were similar to those described in other localizations. Differential diagnosis involves cystosarcoma phyllodes and breast metaplastic carcinoma with chondroid differentiation. The prognosis is likely to be the same as in other chondrosarcomas.
