Huge triple-negative phyllodes breast cancer: a case report

Phyllodes breast tumor is a rare entity of breast cancer. Less than 1% of primary-breast-tumor patients will manifest phyllodes breast carcinoma. To date, no such case report has been published in Asia. A 59-year-old Chinese woman developed a huge mass in her left breast because of phyllodes tumor. The initial symptom of the patient was a solid mass fixed in her left breast. The postsurgical histopathologic results and immunohistochemical stains were consistent with a triple-negative phyllodes breast tumor. The patient received cytotoxic chemotherapy for one course and was recommended to undergo regular examinations every 3 months. Preoperative diagnosis of phyllodes breast tumor remains difficult given its atypical characteristics and unpredictable clinical behaviors at first presentation. Appropriate surgery is the cornerstone of treatment for those patients. Moreover, adjuvant chemotherapy is important in postsurgical treatment for triple-negative breast cancer patients.
