[Cystosarcoma phylloides in adolescent women]

The authors describe four cases of juvenile fibroadenoma (benign form of cystosarcoma phyllodes) in pubertal girls aged 11-15 years. They reflect on the variable behaviour of this rare tumour and differentiate the relations between fibroadenoma, virginal hypertrophy of the breast, juvenile fibroadenoma, giant fibroadenoma and cystosarcoma phyllodes. A dominant position is held by surgical treatment which is strictly individualized. The authors recommend, similarly as many other authors, an extensive excision of the tumour with a safety margin and in case of repeated relapses or the very rare malignant form which frequently behaves as a benign tumour. The operation is made in the submammary groove or on the lateral margin of the breast which ensures an excellent cosmetic effect. The authors do not consider excision of superfluous skin or reconstruction of the breast necessary with regard to the elastic properties of the skin and the capacity of the mammary gland to develop.
