Phyllodes tumors are rare fibroepithelial breast tumors, which are sometimes difficult to preoperative diagnoses and have unpredictable clinical outcome. Malignant transformation of phyllodes is extremely rare. These tumors must be suspected in patients with rapid-growing breast nodules, with a history of local recurrences to avoid inappropriate management.

We report a case of a large phyllodes tumour of breast with malignant transformation in a 45 year old lady.
