[Primary sarcoma of the mammary gland]. / Sarcoma primario de la glándula mamaria.

BACKGROUND: Breast cancer occupies the chief place in incidence after the cervix. This gland sarcomas are rare with less than 1% at this location. Its diagnosis is difficult and its evolution is aggressive.

It was decided to perform right total mastectomy and pectoral muscle resection reconstruction with latissimus dorsi more and histochemical review pathology diagnosed with malignant mesenchymal neoplasm, osteosarcoma osteoblast osteoclast type and complemented the treatment with radiotherapy and chemotherapy. The prognosis is poor because the five-year survival is less than 40%.

In the surgical treatment of axillary dissection is not indicated and adjuvant treatment with radiotherapy and chemotherapy.
