title: [Development of aggressive cystosarcoma phyllodes after conservative treatment of breast adenocarcinoma].
abstract: The case report is that of patient who underwent tumorectomy plus X-ray therapy for mammary invasive ductal carcinoma. Eight years later a large cystosarcoma phyllodes, developed and quickly recurred after conservative surgery. Reviewing previous mammograms, the authors discovered that at the time of irradiation, there was a small lump which had the appearance of fibroadenoma. It may be that heavy X-ray therapy on a benign epithelial and stromal tumour of the breast, played a major role in the later development of cystosarcoma phyllodes.
