A 32-year-old pregnant lady presented with a rapidly enlarging right breast mass. A fine needle aspiration was suggestive of a malignant phylloides tumour. However histopathological examination after mastectomy revealed a moderately differentiated angiosarcoma. The histopathological and cytological features of this rare tumour together with the diagnostic pitfalls are discussed.
