title: Malignant phyllodes tumor with heterologous differentiation: A rare case report.
abstract: Sarcomas of the breast are rare neoplasms accounting for less than 1% of breast malignancy. A 40-year-old-female with left breast mass underwent wide-excision and on histopathological examination a diagnosis of malignant phyllodes tumor with heterologous differentiation of osteosarcoma and chondrosarcoma was rendered. The heterologous elements were tumor osteoid formation and tumor chondroid formation. The rarity of the lesion was considered for reporting and on follow-up the patient was free of metastasis.
