Skin-nipple-sparing mastectomy: The first approach in primary myxoid chondrosarcoma of the breast

The primary mammary chondrosarcoma corresponds to less than 0,5% of the mammary malignancies. For the period ranging from 1967 to 2014, only 18 cases were reported in the literature. A 41 year old woman found a hard nodule on her external right superior quadrant/axillary prolongation through breast self-examination. The vacuum-assisted core biopsy (VACB) revealed “high grade extra-skeletal myxoid chondrosarcoma”. A skin-nipple-sparing mastectomy with the insertion of a mammary expander was performed. A protocol of adjuvant radiotherapy was also indicated. Until 2013, the gold standard was the radical mastectomy. By 2014, there were two cases of conservative approach to quadrantectomy. To our knowledge, this represents the first case in the literature in which a skin-nipple-sparing mastectomy has been performed on a primitive mesenchymal neoplasm of the breast. Such an oncoplastic approach was performed considering the young age of the woman, to assure the surgical radicality and a better quality of life to the patient.
