Les sarcomes mammaires primitifs au CHU de Brazzaville

Malignant breast sarcoma is rarely observed. We report here the types of this histological variety. We conducted a retrospective study for 13 years (1996–2008). It concerned the locations of primary breast sarcomas histologically confirmed and monitored in the radiotherapy and oncology department of the CHU of Brazzaville. During the study period, 999 cases of breast cancer were observed, and 4 (0.4%) of them were for breast sarcoma. The mean age was 32.7 years, with extremes of 19 and 45 years. The consultation motive was a big tumor (18.6 cm on average), with collateral circulation and no lymphadenopathy. Four types of sarcomas were found: spindle cell sarcoma, rhabdomyosarcoma, malignant hemangiopericytoma, and histiocytofibrosarcoma. Outcome was bad despite mastectomy and chemotherapy.
