Malignant phyllodes tumor with chondro and osteosarcomatous differentiation and secondaries in lungs

摘要

Phyllodes tumor is a rare breast tumor, with neoplastic epithelial and stromal components for 10 cm in size and firm in consistency. She underwent left mastectomy. The histopathology revealed a malignant phyllodes tumor with sarcomatous stromal overgrowth and heterogeneous chondro and osteosarcomatous differentiation. At 2 months after surgery, she reported to us with secondaries in bilateral lungs. We planned palliative chemotherapy in view of good general condition of the patient and lung metastasis. Chemotherapy included ifosfamide, adriamycin and cisplatin as per standard regimen every 3 weekly. After three cycles, her lung metastasis cleared completely. It was planned to continue same chemotherapy for six cycles.
