Malignant phylloides with heterologous elements: A case report

Abstract

Phyllodes tumor of the breast is an uncommon biphasic tumor, occurring mainly in females belonging to the age group of 42 to 45 years. Malignant phyllodes tumor is a rare neoplasm that accounts for 10 to 20% of total phyllodes tumors. Histologically, phyllodes tumors are featured by leaf like projections of hypercellular stroma into the cystic or cleft-like spaces being lined by epithelium. Presence of stromal elements like fibrosarcomatous and heterologous sarcomatous characters are associated with an increased risk of malignant change. Here, we report a rare case of a 50yrs old female patient, who presented with swiftly growing left breast mass that was diagnosed as a case of malignant phyllodes tumor showing heterologous elements in form of chondroid, liposarcomatous, rhabdoid and fibrosarcoma, with marked proliferation of stromal component. The patient was subjected to modified radical mastectomy.
