Phylloides tumor is an uncommon type of breast neoplasm. It is similar to fibroadenoma both in clinical presentation and histologically (microscopic appearance). The more benign-appearing tumor is called phylloides tumor, while the malignant-appearing is called phylloides sarcoma.
Phylloides tumors are treated with surgical excision. Good surgical margin should be achieved since this can recur locally. Phylloides sarcomas are treated with mastectomy or surgical excision plus radiotherapy.
I suggest close follow-up with your oncologist.
