Massive malignant phyllodes tumor accompanied by anemia and ulceration in the breast: A case report.

ABSTRACT

Large malignant breast phyllodes tumors are uncommon in clinical settings. Here, we report such a case to provide a reference for clinical work. A 48-year-old woman identified a lump in her right breast, which eventually grew up to 25 cm × 10 cm and began to rapidly bleed and ulcerate within 3 months. The patient had visible signs of anemia and significant emaciation as a result of the tumor's wasting effect and the protracted course of the disease. The patient underwent a modified radical mastectomy on the right breast. The pathology results obtained after surgery revealed a malignant phyllodes tumor. No adjuvant therapy, such as chemotherapy or radiation, was administered. The patient had no symptoms of tumor recurrence and complications from the surgery after a follow-up of 9 months.
