[Anatomical and clinical deliberations on the phyllodes tumor of the breast]

The authors report on three phyllod Tumours of the breast, two benign and one malignant conditions. They insist on the histological aspect of the tumour, underlining that in the benign forme both, epithelial and mesenchymal components does not present atypies, while in the malignant form only the mesenchymal component gets malign sarcomatous character. The microscopic aspect of the tumour and its clinical evolution are suspicious. The diagnosis can be specified only by the histopathological examination. The origin of the phyllod tumour is not clear and the authors discuss the possibility of its development upon a preexistent tumour, specifically on a fibroadenoma of the breast. The treatment is guided by the microscopic appearances. Generally they perform the ablation of the tumour when its dimensions are not greater then 10 cm. and the simple mastectomy when its diameter exceeds this dimension.
