Giant malignant phyllodes tumor with metastasis to the brain.

We present the case of a 32-year-old African American woman with a giant malignant phyllodes tumor that metastasized to the lungs and subsequently the brain. Her treatment included six cycles of adjuvant therapy with AIM (Adriamycin®, ifosfamide, and mesna) followed by therapy with gemcitabine and docetaxel. A grand mal seizure led to discovery of a 6 × 5 × 5 cm brain mass which was resected. After resection, the patient developed pulmonary edema, repeat seizure activity, and massive intrathoracic progression before succumbing to her disease. This is an unpredictable and understudied neoplasm that can be aggressive and fatal in rare cases.
