title: [Phyllodes tumor in the breast].
abstract: In three women aged 51, 37 and 58 years, with a palpable tumour in the breast, excision and pathological examination led to the diagnosis of 'phyllodes tumour'. During 3-5 years after radical excision, in one patient followed by radiotherapy, no recurrences were seen. This rare breast tumour with a variable clinical course usually affects women between the ages of 30 and 50. There is often a large tumour and (or) rapid growth. Mammography and ultrasound are unhelpful diagnostically. Cytology is unreliable as the tumour is heterogeneous. Histologically the tumour can be benign, borderline malignant or malignant. Surgical excision with a margin of > or = 1 cm is the therapy of choice. The risk of recurrence after insufficient excision is considerable and histological deterioration can occur. Multiple samples, examination of resection margins and investigation into atypia, mitotic activity and stromal overgrowth are essential for making a prognosis and a treatment plan. In case of doubt regarding radicality, surgeon and pathologist should compare views; non-radicality necessitates re-excision.
