MALIGNANT PHYLLODES TUMOR OF THE BREAST WITH OSTEOSARCOMATOUS DIFFERENTIATION

Abstract

Phyllodes tumors are rare biphasic tumors of the breast. The stromal component may show homologous and heterologous sarcomatous elements, including osteosarcomatous differentiation. Here we report a 63 year-old lady who presented with a right breast lump diagnosed as a malignant phyllodes tumor showing predominantly osteosarcomatous differentiation with clinicopathological features.
