Malignant phyllodes tumor with synchronous metastases to axillary lymph nodes, lung at the presentation: a case report and literature review

Phyllodes tumors are rare mesenchymal tumors of breast. Malignant phyllodes tumors can develop metastases to distal organs with spreading hematogenously to most frequent sites as lungs, bone and brain. Regional lymph node enlargement is common but metastasis to lymph node is a very rare phenomenon with prevalence about 1.1–3.8%. In this report, we introduce a case of malignant phyllodes tumor of breast in 57-year-old female patient. Synchronous metastases to axillary lymph nodes and lung were found at the presentation. She was treated with mastectomy combined with axillary lymph node dissection and adjuvant chemotherapy. Axillary lymph node dissection can be considered in case of proven metastatic or suspiciously palpable lymph nodes.
