Abstract

Phyllodes tumors of the breast are uncommon, and 6.2% of phyllodes tumors behave in a malignant fashion. The metastatic spread of malignant phyllodes tumor is mainly hematogenous to lung and bone, and malignant phyllodes tumor metastasizing to the ovary is rare, with only 2 cases reported. We report the third case of metastatic malignant phyllodes tumor to the ovary with a focus on the differential diagnosis of ovarian cancer.

Keywords: malignant phyllodes tumor of the breast; metastasis; ovary.
