Malignant phylloides with heterologous elements: A case report

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.
