Unusual and Isolated Pulmonary Metastasis of Malignant Phyllodes Tumour of Breast

Abstract

Though metastasis to the lung is common, isolated extensive pulmonary metastasis with complete replacement of the entire lung is unusual. We present the fatal case of a 60-year-old female patient in whom the entire left lung parenchyma was replaced by a greyish-white solid mass at autopsy. There was no evidence of tumour elsewhere in the body. She had undergone modified radical mastectomy for phyllodes tumour of the right breast 10 years back. The unusual feature of our case was the presentation of the metastasis occurring 10 years after modified radical mastectomy and completely replacing the whole of a contralateral lung mimicking a primary lung tumour, with no other organ involvement.
