title: Bilateral malignant phyllodes tumours.
abstract: We report a rare example of bilateral primary malignant phyllodes tumours. The diagnosis was supported by the identification of a benign epithelial element in each lesion. The case illustrates the typical dimorphic features of malignant phyllodes tumours. A contralateral tumour should not be regarded as metastatic without histological confirmation.
