Phyllodes tumours are fibro-epithelial lesions that comprise less than 1% of breast malignancies. Hamartomas are tumours formed by a cumuli of various epithelial elements, accounting for less than 5% of benign breast masses [1]. We present a case of a 47-year-old women, with a long standing palpable mass of the left breast whom imaging studies showed two different tumours, with core biopsy diagnosing a phyllodes tumour and fibrocystic changes. The patient underwent partial mastectomy and definitive biopsy confirmed a malignant phyllodes tumour and demonstrated a hamartoma on the other mass. Following surgery, radiotherapy was given. No residual breast lesions have been found in follow-up. To our knowledge, there have not been reported cases of concomitant phyllodes tumour and hamartoma on a single breast.
