Male breast cancer metastasising to the liver: A case report.

Abstract

Breast cancer (BC) remains one of the most common malignant diseases affecting female patients, and it can metastasize to nearly every part of the body. BC is rare in men, and therefore men rarely develop BC liver metastases (BCLMs). However, the present study reports a 55-year-old male patient who underwent surgery 5 years ago for BC. After treatment, the patient was actively followed up regularly. Recently, the patient was examined for chest tightness, and liver space-occupying lesions were found. The upper abdominal enhanced computed tomography images of the patient showed that the liver density was not uniform and that the liver had a mass. A crude needle biopsy was used to examine the liver tumour under the guidance of ultrasound. The pathology revealed that the patient was positive for E-cadherin, oestrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, GATA binding protein 3 and CK7. The patient was subsequently diagnosed with BCLM. The patient was treated with doxorubicin hydrochloride, cyclophosphamide, Docetaxel and followed up regularly. The present case report emphasizes that BC is found not only in women but also in an increasing number of men, and that liver metastasis can occur in males with BC. BCLM is a complex process, and therefore it is hoped this case report will improve the understanding of male BCLM and the mechanism of this disease.
